Orientador: José Eduardo Zaine / Banca: Fábio Augusto Gomes Vieira Reis / Banca: Oswaldo Augusto Filho / Acompanha 01 mapa / Resumo: O processo de urbanização no Brasil ocorre, predominantemente, de maneira desordenada, sem a correta consideração das potencialidades e limitações do meio físico, o que se traduz numa forma de ocupação que pode expor a população e o equipamento urbano a processos geológicos exógenos como inundações e movimentos de massa. Isso é observado no município de Ilhabela - SP, onde a alta taxa de crescimento populacional, somada ao relevo acidentado, intensificam esse problema, evidenciando a necessidade de uma orientação adequada da expansão urbana. Dentro deste contexto, os mapas geológico-geotécnicos configuram-se como instrumentos apropriados para o planejamento da ocupação ordenada do meio físico. Assim, o objetivo da presente pesquisa é o mapeamento geológico-geotécnico da região mais densamente urbanizada de Ilhabela, utilizando a análise integrada de imagens aéreas da área de estudo. A fotoanálise e fotointerpretação das mesmas, somadas a informações obtidas em campo, subsidiaram a divisão e classificação da área de estudo em unidades geológico-geotécnicas, que apresentam uniformidade em relação à morfologia e propriedades geotécnicas. Esse procedimento resultou na identificação de unidades geológico-geotécnicas que foram representadas em 3 escalas com diferentes níveis de detalhes (1:50.000, 1:20.000 e 1:10.000), acompanhados de fichas e tabelas descritivas contendo as características físicas, de uso e ocupação e principais processos atuantes nas unidades, além da representação de seus perfis de alteração e relevos característicos. Os produtos obtidos permitiram uma compreensão abrangente acerca das características do meio físico da Ilha, bem como dos principais fatores condicionantes da ocupação antrópica no mesmo, mostrando-se ferramentas eficazes e adequadas ao planejamento territorial urbano do município-arquipélago / Abstract: The urbanization process in Brazil occurs mainly in a non-ordered way, not considering properly the potentials and limitations of the physical environment, what results in a form of urban development that may expose the population and the urban equipment to external geological processes such as floods and mass movements. It happens in Ilhabela-SP, where the high rates of population growth, combined with its rough topography, increase this issue, highlighting the need of an adequate orientation to the urban expansion. In this context, the geological-geotechnical maps happen to be appropriate tools for the planning of the urban expansion in the physical environment. So the aim of this research is the geological-geotechnical mapping of the most densely urbanized area of Ilhabela, through the integrated analysis of the region's aerial images. The photo analysis and photo interpretation, combined with field data, subsidized the section and classification of the study area in geological-geotechnical units that show similar morphological and geotechnical properties. This procedure resulted in the identification of geological-geotechnical units, which were represented in 3 scales, each with a different level of details (1:50.000, 1:20.000, 1:10.000), and accompanied of profiles and description tables containing its physical and land use characteristics and main acting processes, besides the representation of its alteration profile and characteristic relief. The products obtained allowed a wide ranged comprehension of the island's physical environment characteristics, as well as the main conditioning aspects of it's human occupation, so happening to be useful tools that are appropriate to the urban planning of the archipelago city / Mestre

As obras rodoviárias instaladas nestes planaltos apresentam problemas geotécnicos recorrentes, envolvendo erosões aceleradas e movimentos de massa nos taludes de corte. Os estudos geológico-geotécnicos podem ser aplicados na conservação das obras já instaladas e no planejamento das obras futuras, contribuindo com a redução dos custos de manutenção da via e evitando o desenvolvimento de movimentos de massa que venham a limitar ou impedir o tráfego de veículos, colocar os usuários da via em risco e causar impactos significativos ao meio ambiente. A presente pesquisa apresenta uma sistemática de mapeamento geológico-geotécnico com detalhamento progressivo, em escala regional (1:250.000), escala de semi-detalhe (1:100.000) e escala de detalhe (1:10.000), realizada a partir de técnicas de fotointerpretação aliadas a atividades de campo, com o objetivo avaliar a suscetibilidade do meio físico ao desenvolvimento de instabilidades em taludes de corte de empreendimentos rodoviários. A sistemática de mapeamento aqui apresentada considerou principalmente as propriedades do meio físico: ruptibilidade; tropia; forma de encosta; forma de topo; forma de vale; declividade; altimetria; padrão e densidade de drenagem, permitindo inferir o comportamento geotécnico dos materiais constituintes dos compartimentos cartografados. Também foram mapeados os lineamentos estruturais, que deram suporte à análise das condicionantes estruturais da instabilidade de taludes rodoviários, se mostrando importantes indicadores das relações geométricas entre as descontinuidades dos maciços rochosos e as faces dos taludes. As maiores convergências de evidências desfavoráveis à estabilidade de taludes foram identificadas: nas províncias Paraitinga e Natividade; nas... / Abstract: The instability of natural and built slopes is a recurrent problem on the plateaus of Serra do Mar, fostering a diversity of studies concerning slope instability. The road works installed on these plateaus present recurrent geotechnical problems, involving accelerated erosions and mass movements on cut slopes. The geological and geotechnical studies can be applied to conservation of already installed works and to plan future ones, contributing to the reduction of road maintenance costs and avoiding the development of mass movements that may limit or prevent the vehicles traffic, put road users at risks and cause significant environmental impacts. This research presents a systematic geological and geotechnical mapping with progressive detailing, in regional scale (1:250.000), semi detailed scale (1:100.000) and detailed scale (1:10.000), conducted from photo interpretation techniques allied to field works, aiming to evaluate the susceptibility of the physical environment to the development of instabilities on cut slopes of road projects. The mapping systematic here presented mainly considered the properties: frangibility, entropy, slope form, top form, valley form, declivity, altimetry, pattern and density of drainage, allowing infer the geotechnical behavior of the constituent materials of the mapped compartments. The structural lineaments were also mapped, allowing the analysis of the structural conditioners of road slopes instability, showing themselves important indicators of the geometrical relations between the discontinuities of rock masses and the slope faces. The largest convergences of unfavorable evidences to slope stability were indentified in the Paraitinga and Natividade provinces, in the Pt2, Pt1, Nt2 e Pb zones, in the I, IV, V, VI e VIII unities and in the sectors where the structural lineaments intercept the road route, representing parallel, oblique or perpendicular discontinuities to the cut slopes.

In my diploma thesis, I concern with the detailed geological model of the base of the industrial complex in Kralupy nad Vltavou and the surrounding area. I have collected all available data from geology, engineering, geology, hydrogeology and geophysics. I created a database and using the autoCAD civil3D software and knowledge from the research part of this work I created a 3D model of interest area. From this model, I created maps and characteristic profiles. Based on archival research and created profiles, I reviewed the foundation basement of the most important buildings. My work provides complete geological information of this territory within 60 meters supported by all available surveys by 2016.

Permeable Interlocking Concrete Pavements (PICP) have seen increased popularity in the principles of Water Sensitive Urban Design and Sustainable Drainage Systems in recent years. To address certain design queries that still existed in industry, a two-year experimental study was conducted. It entailed the construction of an Infiltration Table Apparatus and subjecting a representative volume of PICP to hydraulic testing within it. The study aimed at determining the controls of the flow of water into and through these pavements, the effect of variations in construction materials and incline on them, the validity of the hydraulic testing methods currently being applied to them in industry and lastly, to inform on their infiltration rates. A host of permeability data for PICP was gained and it was found that both the choice of materials and the incline on which PICP are constructed, can change their hydraulic properties drastically. In general, the selection of lower permeability materials in the surface portion of the layer works decreased the overall permeability of the pavement, while increases in inclines did the same. In addition, it was found that field investigation techniques require revision and further innovation before they can be effectively applied to PICP. / Dissertation (MSc)--University of Pretoria, 2019. / Bosun Brick (Pty) Ltd. / Geology / MSc / Unrestricted

El objetivo de esta investigación fue examinar la relación entre los factores críticos de éxito del perfil de implementación del proyecto (PIP) con los criterios para medir el éxito del proyecto, y el grado en que varían las relaciones al ser moderadas por la experiencia, la certificación en gestión de proyectos, y el estilo de liderazgo transformacional del director de proyecto. El estudio fue no experimental, de naturaleza cuantitativa, y realizado en Perú y Ecuador para el sector de tecnologías de información (TI). Los datos fueron obtenidos por encuestas y modelados utilizando ecuaciones estructurales. Los resultados muestran que los factores críticos que explicaron el éxito fueron la aceptación del cliente, el equipo del proyecto, y la resolución de problemas. La experiencia del director de proyecto no es significativa y la certificación no incide en el éxito. Se concluye que durante el desarrollo de un proyecto es necesario combinar varios estilos de liderazgo. / The aim of this study was to examine the relationships between the critical success factors of the project implementation profile (PIP) with project success criteria and with the degree to which relationships vary when moderated by experience, management’s project approval, and the transformational leadership style of the project’s manager.

The Yazoo Clay is a calcareous fossiliferous mudrock that outcrops in a northwest-southeast belt across much of Mississippi and in adjacent states. Based on over 240 X-ray diffraction analyses, the average composition of the Yazoo Clay is 28% smectite, 24% kaolinite, 22% quartz, 15% calcite, 8% illite, 2% feldspar, and 1% gypsum. Exposed Yazoo clay is weathered to a depth of 30-40 ft. and has a distinctive yellow/brown color; unweathered Yazoo is blue/gray. In most wells, smectite is more abundant in weathered clay than in unweathered clay. Mineralogic changes correlate well with engineering properties of the samples, which in general show a decrease in plasticity indices with depth. Weathered Yazoo clay exhibits greater mineralogic variability than unweathered clay. Mineralogical content also varies laterally. Lateral variation, along with correlative smectite content and engineering properties, is the reason for ?roller coaster? roadways and structural damage caused by the swelling Yazoo Clay.
