The Classic Methods and their Further Developments
The classic methods of tunnelling were no less audacious than modern methods and the experience of the engineers of the time was at least as good. This chapter describes the most significant basic principles of through the example of former tunnels. The usual names according to countries are used in the chapter combined with the most important process principle in each case, like German or core method, Belgian or underpinning method. The chapter begins with a discussion on full‐face excavation. The excavation of a partial section is always followed by the installation of temporary support. The chapter lists the reasons that can lead to a decision to excavate a section in parts. According to its traditional development, shield tunnel driving also belongs to the classic tunnelling methods. Detailed shield processes were designed and described long before the engineering development of the classic tunnelling methods.
