After several years of attenuatin of underground construction in our country is gradual re-expansion in its prospect, related to the planned traffic tunnels and in particular the construction of a new metro. A major issue is the implementation of the BIM methodology in underground construction, which will be devoted to one part of the project. To keep up with the developed countries, timely understanding and implementation of the BIM is crucial. The topicality of the project part on mechanized tunneling is based primarily on the need of the Czech underground construction industry to deal in detail with the design of the segment lining used to secure the cavity in mechanized tunnelling together with all the specifics of its operation and technology. Another separate part of the project is the theme of conventionally excavated underground structures lining made of sprayed fiber concrete. Motivation for the use of fiber concrete for underground constructions results from the possible reduction of construction time, increased safety of work and more efficient execution of excavation. The solved issue is currently up-to-date mainly abroad, but it also offers great potential in the Czech Republic and Slovakia.

Underground constructions are experiencing a worldwide boom in recent years although in our conditions they are currently undergoing an attenuation. The culprit is the general downturn of the construction industry and the high cost of underground works. This is why this time should be devoted to the research that would result in a reduction of price of underground structures and also into a greater confidence in their usefulness through bringing a new knowledge into current practice. The methods used to both design and implementation are constantly modified, updated and improved. In Czech Republic we meet a certain reluctance to adopt new knowledge and also not very creative approach in the design phase of construction. Using a new technology is accompanied by problems stemming from ignorance and distrust of decision-makers. Underground structures especially of transportation, but also of municipal character, are designed in increasingly complicated conditions, with shallow overburden and very often in urban areas. Given the extensiveness of the problem, research is divided into several parts. The first part of the research will be to analyze the behavior of the primary excavation support during excavation according to NATM principles, namely the distribution of internal forces for the real shape of the primary lining and investigating the behavior of the supporting rock ring. When considering where to develop design of underground structures we should face the current issues and needs. To be able to design more sophisticated structures we should keep ourselves informed on the latest research of new technologies and follow up with our own research and development. One of the recently heavily discussed technologies in underground structures is the use of fiber reinforced concrete.

Given the extensiveness of the problem, research is divided into several parts. Following the SGS 2014 the effect of advance-core reinforcing by fibreglass anchors during the excavation of the tunnel and its effect on the strain response of the rock mass in its full scope will be solved. This topic proved to be highly relevant and interesting for professionals. The research will therefore be devoted to a deeper understanding of the stress-strain processes in the foreground of the tunnel face (in the advance core-face) and the possibility of using horizontal anchoring as an element of the tunel primary linig. Considering all the new requirements resulting from currently introduced technologies, it is necessary to keep up in terms of design activities as well as geotechnical monitoring. Therefore there will be an independent part of the project which will concern geotechnical monitoring. This part will be focused on the deeper study and research of parasite

The culprit is the general downturn of the construction industry and the high cost of underground works. This is why this time should be devoted to the research that would result in a reduction of price of underground structures and also into a greater confidence in their usefulness through optimization of numerical modelling and bringing a new knowledge into current practice. The methods used to both design and implementation are constantly modified, updated and improved. In Czech Republic we meet a certain reluctance to adopt new knowledge and also not very creative approach in the design phase of construction. Using a new technology is accompanied by problems stemming from ignorance and distrust of decision-makers. Underground structures especially of transportation, but also of municipal character, are designed in increasingly complicated conditions, with shallow overburden and very often in urban areas. The recent rapid increase in the capability of computers and increasingly user-friendly software had led to a proliferation in the use of numerical analyses in design of underground structures. One important fact is often overlooked. No matter how sophisticated a numerical model is, it is only an approximation of the real case. Therefore, the proposed research is to optimize the implementation of numerical calculations of underground structures to achieve maximum compliance with reality. The results of research should be recommendations for designers of underground structures using numerical modeling with regard to the application software and input data.

Underground structures especially of transportation, but also of municipal character, are designed in increasingly complicated conditions, with shallow overburden and very often in urban areas. Therefore, the funding from feasibility studies to actual implementation is very complex and expensive. The recent rapid increase in the capability of computers and increasingly user-friendly software had led to a proliferation in the use of numerical analyses in design of underground structures. It must not be overlooked, however, that only a designer with a good theoretical basis and practical experience is able to enter the model and evaluate the results accordingly. Another difficulty of these programs is no matter how sophisticated a numerical model is, it is only an approximation of the real case. Only if this deviation is known, it can be effectively reduced or eliminated. Therefore, the proposed research is to optimize the implementation of numerical calculations of underground structure
