3D FEM Design of the Technical Chamber of the Hlavka Bridge Collector in Prague
Abstract: The construction of utility tunnels network in Prague started in 1969 and it is enlarged by Hlávkův Bridge Collector now. This utility tunnel connects the already existing collector lines both on the left bank and right bank of the Vltava river and it makes permanent relocations of all utility networks installed on the Hlávka Bridge possible. The project of Hlávkův Bridge utility tunnel...

Analysis of Tunnels Using Latin Hypercube Sampling
Abstract: The paper is focused on the Latin Hypercube Sampling method (LHS) which can be successfully utilised for description of the variability of the soil and rock mass in the geotechnical design. It gives a brief description of the input parameters as random quantities and describes the LHS-mean method in detail with the focus on methods for statistical dependence. The main part of the paper is then...

Back Analysis of Brusnice Tunnel based on Neural Networks
Abstract: The Brusnice tunnel is an important part of the Prague City Ring Road. The tunnel was excavated using NATM method (mostly in shales and deluvial sediments). The geotechnical monitoring was carried out during construction and its results give a good opportunity to perform a back analysis. After a short introduction, the authors briefly describe the selected cross-section, the geological...

Numerical Models of Tunnels and Eurocode7
Abstract: In the Czech Republic, it has been common practice to design geotechnical structures using the limit states method since early 1960s. This methodology implemented in the Czech standards was clear and well-defined approach that was in general accepted and lead to safe and economic design. With the introduction of EN 1997-1 „Eurocode 7: Geotechnical design – Part 1: General rules“, the engineers...
