Finite element analysis of a deep excavation A case study

A total of 18 underground stations were constructed using the Top-Down construction technique, together with diaphragm walls (D-walls) and concrete slabs as excavation supports. A total tunnel length of 20 km was created using eight Earth Pressure Balance (EPB) shields. The excavation depths and D-wall lengths are plotted in Fig. 2.

Behavior of Deep Excavations Using Sheet Pile Bracing

Jun 03, 1993 · The sheet pile bracing system is the most well-known for excavation work in Bangkok soft marine clay. The sheet pile wall which is defined as flexible wall will show a large significant of lateral deformation and ground surface settlement if the excavation system is carried out without a good quality control. The sheet pile bracing system with fully effective …
