Drilling technique and technology related to engineering geology
Šula, Igor ; Novotný, Jan (advisor) ; Rout, Jiří (referee)
The publication serves for information about drilling in geology, it describes histrorical context of drilling in the distant past and its purpose but also the reader is introduced with the complex logic of drilling and knowledge of drilling techniques. Simultaneously this publication describes borehole together with all works which must be done before bigger projects of drilling begins. Because the publication isn't only about drilling technique and technology so basic informations about ground investigation methods are in this publication too. Key words: borehole, drill rig, drill bit, core, ground investigation

Development of calibration methods for hypoplastic models
Šula, Igor ; Mašín, David (advisor) ; Janda, Tomáš (referee)
The calibration application named ExCalibre was developed at Technical University in Prague, Faculty of Civil Engineering. This application can automatically process experimental data and create set of parameters of hypoplastic models which are designed for saturated clays or sands. The aim of this master thesis was to support development of application for calibration with testing it on real experimental data sets. Automatic calibration of these data sets was compared with calibration by hand for identical data. The development of the application and main phase of testing took place in two stages, where the main calibration errors of calibration application were identified. After the final testing of application where the minor bugs and errors were overcome a user-friendly web application (soilmodel.com/excalibre/) was introduced. This final testing has gone beyond this thesis. The results from the main phases of testing are discussed in this thesis as well as the description of database of fine-grained and coarse-grained samples which were used to testing of application. Knowing the calibration of the model is crucial for its using, you can find description of the used constitutive models in this thesis, which are used in the calibration application, as well as a description of procedure for...
