Abstract
Proposed research works and mechanical analysis of geological and synthetic materials are basis for different models which can determine relationships between the ground layers and constructions above and below ground surface which are exposed earthquake loadings. The planned construction in the complex geotechnical environments and opportunities to use modern engineering materials with the aim of providing economic and safe construction method, is of the utmost importance for the future development of technologies with excellent usable in the changing geological conditions. Laboratory and field studies and investigations of geomechanical parameters of different soils and rocks including high squeezing ground layers, which are ongoing and will be implemented in the near future, will enable a determination of the appropriate geotechnical characteristics and interactions of physical and chemical links with the aim of achieving a better knowledge of the time-dependent deformation processes. Numerical modeling of the various relationships between natural geological materials and artificial support systems in soils and rocks and not at least high squeezing grounds will be improved in terms of in-depth scientific examination of such relations. The research will focus on geotechnical modeling. The obtained findings will be applied to problems that pose a risk to geotechnical engineering. In the geotechnical modelling, we will explore existing and develop new and more sophisticated geomechanical models for the analysis of limit states for homogeneous and heterogeneous foundation ground. Risks in geotechnical engineering refer to risk and safety in construction, mining, geotechnical engineering and environmental protection. It includes analyzes, assessments and decisions in the planning of infrastructure and buildings, taking into account all the uncertainty and all possible consequences. The risk analysis and reliability is a multidisciplinary field that for the analysis of the probability, reliability and analysis of decision includes several engineering disciplines. Scientific knowledge, based on the results of fundamental research of mechanical soil and rock properties with possible applications in the wider area of ​​rock will largely facilitate and contribute to technical decisions in the development of new technologies applied in the wider environment. These decisions will be indirectly confirmed by the accompanying measurements and observations at the ground surface and underground facilities. Belong that all respects will be included in the principles of sustainable development of individual sites on the earth's surface.
Significance for science
Predicting the ground’s geomechanical properties under different environmental conditions is possible only if the key factors that determine them are known. Among them are, certainly, the most important mineralogical properties of soils, primary stress state and degree of tectonic disturbance. Analyzing the interaction between the mineralogical and geomechanical properties of soils is completely new research area in the world with a few researchers who work on this field. The reason is that described topic covers four research areas, namely geotechnology, the civil engineering (geomechanics), geology (mineralogy and petrography) and physical chemistry, therefore, the interdisciplinary knowledge is necessary. The proposed topic of research in geotechnical modeling is relatively new in the world, but because of the need to understand the consequences of human activities affecting the environment connected with economic principles of construction ever more up-to-date. Some of the existing models, which are mainly useful for the analysis of homogeneous soil and rock environment will be completed and generalized to be applicable also in cases of layered soils and high squeezing grounds. The proposed research project should therefore continue to do research, which are already so far, due entirely different, more theoretically based approach, encounter great interest of researchers in the world. Very deep analysis of the behavior of underground structures in tectonically active rocks using 3D geomechanical modeling will contribute to a better understanding of the relationship rock - support system, which is the basis for practical applications in the construction of underground nuclear facilities. In this way, the scientific proven benefits will be carried out, because the comparison between underground and surface facilities in seismically active areas shown a big advantages from first one. It is known that current measurements and observations of damages of underground facilities that were under the influence of earthquake loads have showed an extremely good static resistance against crushing. Lessons learned will be highlighted criticism of the wider professional public with the publication of research results in major scientific journals.

Significance for the country
Development of methods that allow more accurate and reliable results of geomechanical investigations is essential for safe and rational construction and the environment protection (landslides). For geotechnical modelling, we also intend to consider the effects of environmental conditions that may be changing, and differ from case to case. The geotechnical modelling will allow us more real and optimal solutions of practical problems. The result of latter will be more rational and more reliable construction, first of all of very exacting geotechnical structures that are increasing due to better exploitation of the environment. Special attention is given to scientific knowledge about the behavior of underground structures in tectonically damaged rocks that are exposed to seismic activity. Based on the results of the 3D geomechanical modeling of relationships between rocks and supports systems, taking into account the seismic loads, will be possible to design high-quality underground nuclear facilities in rock environment with discontinuities. Viewed from a broader perspective of ensuring the safety operation of nuclear power plants, which are exposed to seismic loads, and taking into account the damage caused in the disaster in Fukushima (Japan) 2011 estimate is around $ 350 billion, is the real construction of underground nuclear power adequate solution for electricity generation. Developing methods which allow more accurate and reliable results of geotechnical investigations is essential for the safe and efficient construction of increasingly complex infrastructure and environmental protection. Development of methods that allow more accurate and reliable results of geomechanical investigations is essential for safe and rational construction and the environment protection.
