Frost susceptibility of soils and waste materials to pavement subgrade
Sokolová, Veronika ; Mondschein,, Petr (referee) ; Stehlík, Dušan (advisor)
Destruction of road constructions due to the frost is in locations with temperatures under the zero a problem which leads to permanent deformation. The theoretical part of this thesis deals with the freezing process of the pavement and its subgrade. It presents methods for determining the rate of frost susceptibility in both the Czech Republic and abroad. Describes the materials used in the subgrade of roads and their suitability in terms of frost susceptibility. The thesis closely examines the fly-ashes, their properties and possibilities of using in the construction industry. The practical part of the thesis focuses on the performance of direct laboratory frost heave tests, immediate bearing index tests, California bearing ratio tests and cyclic load triaxial tests to determine the modulus of elasticity. Tests are carried out on the soil, the soil mixtures with certain percentages of fly ash from different sources at the same soil treated with lime. Then the results are compared and dependence between the measured characteristics of materials is created.

Detection of water infiltration into soils injected by clays using EIS method
Marek, Ondřej ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The diploma thesis deals with the study of water infiltration into soil samples with various types of clay. The soil matrix was represented by homogeneous sand; clay samples were supplied by LB Minerals, Ltd. Soil analysis with injected clays was focused on sealing ability of examined clays for possible use in construction practice for the construction of sealing objects. Electric impedance spectrometry (EIS) measuring system was used to monitor the infiltration process. The measurement was carried out by a measuring apparatus made by the solution of the international project E! 7614 of applied research in the EUREKA program within its sustainability.

Verification technology BioSealing by EIS method
Fránková, Hana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
Diploma thesis is dealing with recognition of Biosealing technology using electrical impedance spektrometry method. BioSealing is an innovative method of soil body reconstruction, which uses stimulation of soil bacterial activity to seal the leakage. The method was developed in the Netherlands and it was used in conditions of the Czech Republic in years 2015 and 2016 on the Hornice water work. This earth dam was monitored by electrical impedance spectrometry by apparatus with device Z-meter IV in this period and the data are processed and assessed in this diploma thesis.

Estimating soil effective grain size by EIS apparatus
Chládová, Zuzana ; Novotná, Jitka (referee) ; Pařílková, Jana (advisor)
The bachelor thesis is focused on the use of electrical impedance spectrometry and its possible application in the estimation of effective particle size of soil. The grain size curve of each soil sample was obtained by using the sieve analysis and aerometric method after which the effective particle size for each sample was determined. Thereafter the frequency analyzes of samples were performed under laboratory conditions using Z-meter. The results showed that it is possible to infer effective particle size when the frequency analysis is performed for example during field measurement. This research was carried out as part of the project E!7614 of the EUREKA program.

Verification of nonlinear material models
Prokš, Tomáš ; Němec, Ivan (referee) ; Hradil, Petr (advisor)
The bachelor thesis deals with verification of nonlinear material model of soil FHWA SOIL during shear test. The nonlinear problem was being solved by software LS-DYNA using explicit formulation of finite elements method. The values of horizontal displacements during the direct shear test were compared with the results listed by the developer of the material. The considerable difference in the results led to focusing on the settings of the material model and influence of application of load, geometry and type of finite elements on the monitoring values.

Design of foundation of library building
Habanec, Kamil ; Novotný,, Petr (referee) ; Zich, Miloš (advisor)
The master’s thesis deals with the static solution foundation structure of the Moravian-Silesian Scientific Library in Ostrava. The goal is to process the design for the commissioned construction of the library building in detail, numerically and graphically, on the foundation supporting structure of the underground floors. Subsequently, their static solution, dimensioning and assessment for limit states. The solved elements are the foundation slab in the second underground floor, the bearing capacity of the piles and the foundation block of the core A. The static analysis was performed in a combination of the student versions of SCIA Engineer 22.0 and the Midas program. The work also includes drawing documentation for the above-mentioned elements. The calculation was carried out according to applicable standards and principles.

Evaluation of changes in pond dam monitored by EIS Method
Novák, Michael ; Maleňák,, Jaroslav (referee) ; Pařílková, Jana (advisor)
The bachelor's thesis deals with the evaluation of monitoring of earthen dike of fish pond which was built near the municipality Jevíčko. To identify the observed changes, which are related to variable loads earth dike with water, in time and space has been selected indirect electrical method of measuring electrical impedance spectrometry. This method is described in the work and the results of monitoring are published in graphical form and are commented.
