Numerical Simulation in Tunnelling

The book presents results of the joint research initiative (FSP) "Numerical Simulation in Tunnelling". The aim of the FSP was to further develop existing numerical simulation methods so that they can be applied at the tunnel site to a greater extent than currently done. The purpose of this work was to achieve a good correlation between numerical prognosis and the actual in situ behavior. The technical aim of the FSP was to develop and apply numerical simulation tools to estimate the required tunnel support, the required construction measures and their impact on the environment at the planning stage and during construction. This results in an improvement of the safety and economy of tunnels. Different aspects are considered, from the acquisition of data to the development of efficient algorithms for the numerical simulation of tunneling in highly deformable soil. After an introductory chapter, which examines the need for technological development in the area of data acquisition and numerical simulation the results of the FSP are presented. Each individual project is assigned about two chapters.
