Influence of temperature on the rock stress distribution and slope stability
Racek, Jonáš ; Blahůt, Jan (advisor) ; Kycl, Petr (referee)
This thesis deals with the influence of cyclic temperature changes on the surface of a rock mass on temperature and stress fields inside the rock slope and their influence on local and overall slope stability. The review part deals with the evolution and stability of rock slopes with a focus on temperature oscillations. Furthermore, thermal parameters of rock masses, rocks and minerals are discussed. In the practical part a 2D numerical linear-elastic model of the response of the rock slope Pastýřská stěna in Děčín to cyclic temperature changes during different periods was developed. It was used to determine the depth of penetration of temperature cycles and the associated changes and redistribution of stresses within the mass and the zones susceptible to mechanical failure of the rock. iii

Compilation a digital 3D engineering geological map in scale 1:5 000 map sheet 6 - 8 Kralupy nad Vltavou
Kalinová, Radka ; Kycl, Petr (advisor) ; Pospíšil, Pavel (referee)
The dissertation be about use the opportunity of 3D modelling geological settings for definitions engineering geology zoning. The model area represents the map sheet 6 - 8 Kralupy nad Vltavou in scale 1:5 000, which is built by rocks (pre-Quaternary) and soils (Quaternary cover) divided into eleven engineering geology zones. The results of modelling are showing at the map appendices, which are engineering maps all of nine the individual roof (surface) of zones, including the 3D section in the direction of x axis and also five of the 2D maps of roof of selected zones with the 3D schematic models. The integral part is the map of documentation points and their database on DVD. Three dimensional modelling presents a benefit mainly therefore the solutions, where are visible the spatial geological settings including the thickness individual layers, respectively zones. These display options can have practically used at designing underground buildings, e.g. tunnels, where would it mean shortening time the preparation of the project. Modelling of the zones also shown a possibility of distinction the mistakes at some archive hole. For example, the mistakes in descriptions can relate to confusion of Neogene's sand layer for Quaternary's sand. In the description of new geological survey, when using appendix no....

Slope deformation risk assessment in the area of Prackovice after floods in 2013
Roháč, Jakub ; Kycl, Petr (advisor) ; Florián, Tomáš (referee)
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.

The risk assessement of slope deformations for the R35 Highway project in the region of the southern by-pass of Turnov city
Dašková, Barbora ; Kycl, Petr (advisor) ; Krejčí, Oldřich (referee)
The planned R35 expressway has been known in paper form since 1963, but to date only a few sections have been built. These include the planned stretch through Bohemian Paradise. There are several ways to drive the highway, but none of them is perfect. So far, the winning northern variant has a planned southern bypass of Turnov using a tunnel to lead under the villages of Mašov, Hamry and Pelešany. Unfortunately, this area is known as a temporarily soiled landslide area. This thesis deals with the detection of the sliding surface of the sludge by means of geophysical measurement of ERT, mapping of the studied slope in the scale of 1: 5000 and possible impacts of the built tunnel on the municipalities. The mapping took place in March 2016 and together with the documentation points, is a map of the annex to this thesis. Keywords: R35 road, tunnel, ERT, slope stability, landslide mapping

Construction of a purpose-built engineering geological map M 1:5000 of a selected area of Prague-Radlice elaborated on the basis of detailed field mapping
Roháč, Jakub ; Kycl, Petr (advisor) ; Chmelař, Radovan (referee)
This work deals with constructing a detailed purpose-built engineering geological 1:5000 map of a part of Prague 5, where the tunnel of "Radlická radiála" will be excavated. This radial is designed to connect the motorway ring with the street circuit. The mapped territory is sparsely built-up, only a small part of the area on the north-east side is covered by single-family houses, on the west side there is an old brick-kiln. The subsoil is made up of paleozoic rocks which are covered with rocks from the cretaceous and quaternary age. The map is primarily designed as exposed. It was constructed using archive materials but also a detailed terrain mapping. In the work I describe the geological, engineering geological and hydrogeological conditions of the area and I create a purpose-built engineering geological map and a map of documentation points. The engineering geological map serves only as a reference base. The realization of tunnel construction will require a detailed engineering geological research.
