Zhodnocení sesuvného rizika v oblasti Prackovic po povodních 2013 / Slope deformation risk assessment in the area of Prackovice after floods in 2013

Roháč, Jakub January 2015 (has links)
This thesis deals with constructing engineering geological 1:1000 map of Dobkovičky landslide, collecting of reconstituted soil samples, their laboratory CIUP triaxial testing and subsequent modeling of wall stability of the landslide after the excavation of collapsed soil material. Mapping was done during spring of 2014. Outcome of this thesis is hand drawn map, plotted on the map are all the elements of the landslide including 38 documentation points. Legend of the maps is attached. Collection of reconstituted soil samples was done during drilling investigation, executed by company AZ Consult, spol.s.r.o., during summer of 2014. Three samples of all that were collected were subjected to laboratory CIUP triaxial testing. The result of the testing is critical friction angel, which was used during modeling of wall stability of the landslide after excavation of all collapsed soil material. For the actual modeling, PC software Plaxis 2D was used.

Magnetická stavba, tok magmatu a tektonická deformace ve vulkano-plutonických systémech / Magnetic fabric, magma flow and tectonic deformation in volcano-plutonic systems

Tomek, Filip January 2015 (has links)
Magnetic fabric, magma flow and tectonic deformation in volcano-plutonic systems ABSTRACT This Ph.D. thesis aims to investigate dynamics of emplacement and tectonic history of selected volcano-plutonic complexes in a continental magmatic arc and back arc setting. The thesis presents new data sets from five field areas, presented in separate chapters, which could be viewed as representing a vertical sections through upper part of an intermediate to felsic magmatic system. From top to bottom in this ‛imaginary' vertical system, the examined units are: (1) andesitic lava domes and (2) sub-volcanic magma chambers (<3 km deep) of the Miocene Štiavnica volcano- plutonic complex, Western Carpathians (Slovakia), (3) Shellenbarger pluton (<3 km depth) within the mid-Cretaceous Minarets caldera, Sierra Nevada batholith in California (USA), and ~7-10 km deep granitoids of (4) Lower-Cretaceous Wallowa batholith, Blue Mountains province in Oregon (USA) and (5) Late Devonian Staré Sedlo complex, central Bohemian Massif (Czech Republic). The research incorporates extensive field and structural data, supported by analysis of igneous textures and anisotropy of magnetic susceptibility (AMS). The latter is further accompanied by detailed examination of magnetic mineralogy using thermomagnetic measurements and optical and back...

Polyfázový strukturní vývoj rozhraní suprastruktury a infrastruktury v orogenních zónách / Polyphase structural evolution of superstructure and infrastructure in orogenic zones

Peřestý, Vít January 2012 (has links)
Polyphase structural evolution of superstructure and infrastructure in orogenic zones Proterozoic basement rocks of the Teplá-Barrandian Unit (TBU) are affected by two main tectono-metamorphic events. The central and SW part of the TBU is a well-preserved relict of Cadomian episode. On the other hand, the western margin of the TBU shows superposition of polyphase early-varicsan deformation and metamorphism onto the pre- variscan fabric. The Střela river profile in the northern part of Teplá Crystalline Complex (TCC) exposes a continuous crustal section through western margin of the TBU from the low-grade phyllites (near biotite izograd) in the east to the high-grade rocks of kyanite zone at the contact with high-pressure Mariánské-Lázně Complex (MLC). Three main deformation events were distinguished in the studied area and the cross-section is interpreted as a fossil (devonian) suprastructure-infrastructure transition zone preserved in the carboniferous TBU superstructure. The oldest pre-variscan D1 phase produced flat-lying metamorphic foliation showing normal metamorphic zonation from the very low-grade in the upper part to at least garnet zone in the structurally lower part. Large scale upright folding of prevariscan foliation S1 occurred during early-variscan D2 event. Tight F2 folds were...

Rozšiřování konce trubky za dynamických podmínek / Tube Flaring Technology under Dynamic Conditions

Macháček, David January 2017 (has links)
This master thesis is divided into three main parts. In first part is more closely described the method of tube flaring. Tube flaring was chosen for analysis of biaxial stress, in this thesis particularly in the presence of high strain rate. In the second part is more closely described influence of high strain rate on the forming process. There is described influence of high strain rate on behavior of the material, hardening, change of quasi-static yield strength to the dynamic yield strength, influence of high strain rate on the microstructure and more. During the description of these processes there is effort to describe the cause of these changes as well. For this task was used domestic and foreign literature, as well as peer review papers whose authors study intensively this problematic. Besides all of the above there is also derived the velocity of elastic and plastic wave. In the end is evaluated experiment, in which was done tube flaring, which is part of this master thesis. Results from the 3D optical system ARAMIS are interpreted with the help of Microsoft Excel, where the chosen results were used as the input to the equations modified for the dynamic loading.

Studium deformace kruhových otvorů v závislosti na jejich odstupu od ohybu při dvoubodovém ohýbání na ohraňovacím lisu / Study of the deformation of the circular holes in relation to their spacing from the bend in the two-point bending of the sheet on the bend press

Piterka, Miloslav January 2018 (has links)
The thesis is focused on studying deformation of the circular holes in the limit bending space, depending on the material type, distance from bend, the thickness of material and diameter of hole. After analyzing all necessary technological parameters was bending technology on press brake selected. An experiment for which the tools and press brake Trumpf TruBend 5170 were selected was designed and performed. Samples for the study were designed, bent and measured. The charts have been prepared for practical use in the company from measuring. In addition, simulations were processed in Ansys program and graphs were compiled to compare the main effect of the hole deformations. Two methods were chosen to prevent deformation in limit bending space. Under-cutting method by laser and method of using special Rollbend tool. In the end, economic studies for the Rollbend tool were developed instead of under-cutting hole with grinding.
