This book presents all construction methods for the planning and execution of modern tunnel structures, starting from the geological situation. The excavation methods, such as blasting, tunneling with partial cutting machines, and tunnel boring machines in rock and loose material, as well as specialized tunneling methods for crossing fault zones, are described in detail. Additionally, modern logistics systems for supply and disposal, as well as site setup and production facilities, for example, for segment production, are explained in detail. The highly mechanized securing and expansion methods complete the explanations of the construction operational processes.
