Abstract

Constant monitoring of the ground behaviour and its interaction with immediate support elements has resulted in the highly successful excavation of the 160m-long × 256m² undersea crossover chamber for the British side of the Channel Tunnel. Excavated according to the NATM, constant observation of ground movement and other related data allowed for immediate changes to ensure controlled excavation and installation of adequate immediate support. This paper describes the excavation methods and geomechanical properties of the site.
