[pt] ANÁLISE DE TENSÕES E DEFORMAÇÕES EM PAVIMENTOS / [en] ASSESSMENT OF THE ALTERABILITY AND GEOMECHANICAL BEHAVIOUR OF ROCKFILLSPAULO CESAR DE ALMEIDA MAIA 31 October 2001 (has links)
[pt] Os pavimentos nada mais são que um sistema de múltiplas
camadas, solicitados por um pneumático. Nas últimas três
décadas inúmeras pesquisas tem sido direcionadas para o
estudo de pavimentos. Porém, estas são complicadas, pois os
pavimentos são estruturas físicas com interações de um
grande número de fatores complexos e interdependentes.
Dentre esses,podemos citar os parâmetros geotécnicos dos
materiais, as características geométricas das camadas, a
forma e intensidade do carregamento e fatores naturais.
Este estudo consiste na análise paramétrica de um sistema
de múltiplas camadas,representado por um pavimento
constituído de base, sub-base e subleito. São apresentados
gráficos normalizados de tensões e deslocamentos,
resultados de uma análise por elementos finitos,
utilizando, para isso, o programa LUSAS.
Com base nos resultados, são analisados aspectos com
relação ao desempenho do sistema, tais como: geração de
poro-pressão, zona de tração, solicitações drenadas e não-
drenadas,variação da geometria do conjunto e variação das
propriedades geotécnicas dos materiais. Este estudo também
compara os resultados encontrados com outras proposições.
É verificada uma forte dependência do comportamento de
pavimentos com relação às suas características geométricas
e propriedades geotécnicas. / [en] This work presents an experimental study of the behavior of
rockfills, focusing on the changes caused by rock
alteration on the physical and mechanical characteristics,
such as, lithology, gradation, deformability and strength.
The basalt rockfill used in the construction of Marimbondo
dam has been considered, with about 25 years of in situ
alteration, together with intact basalts samples from Rio
Grande quarry, which is located about 500m downstream from
the dam site. The experimental results were also compared
with data from tests on granite rockfill samples from Serra
da Mesa dam. A methodology is proposed for evaluating the
alterability of rockfills, based on laboratory tests on
intact and alterated samples. Procedures for fast rock
alteration in the laboratory were also developed,
attempting to simulate the naturally slow alteration which
occurs in the field. The laboratory alteration made use of
both continuous leaching and wetting-drying cycles on
intact basalt samples. The leaching was imposed in a large
scale soxhlet equipment developed in the geotechnical
laboratory at PUC-Rio. For the characterization of the
geomechanical behavior of the rockfill masses, large scale
equipments have been used, such as an confined compression
chamber, triaxial compression machine and direct shear box.
The results indicate that the intrinsic characteristics
play an important role on the rockfill behavior.
Furthermore, basalt alteration occurring in the field or in
the laboratory may cause a significant decrease on the
rockfills stiffness and strength parameters, as well as na
increase on the abrasion characteristics of rockfills
particles. This study also indicates that leaching in large
scale equipment is a proper way to simulate the basalts
natural alteration in accelerated laboratory conditions,
making possible the long time prevision of the behavior of
rockfills. Considering a time period of 75 years of natural
alteration in the field, this work presents a quantitative
prediction of Marimbondos rockfill behavior in terms of
particle breakage, abrasion resistance, compressibility
modulus M, deformability modulus E, unconfined strength qu
and strength envelope parameters.
