Drilled-pile wall for deep excavation at Frederiksberg Station, Copenhagen

摘要

Deep excavation at a densely populated area is always a difficult task. In this paper the design and performance of a pile wall for a deep excavation in the centre of Copenhagen city is presented. Here it was possible to use drilled pile wall, a veryflexible pile wall instead of a stiff concrete diaphragm wall. This solution is very economical and very competitive with other methods. The use of the FEM method with Plaxis makes it possible to design the optimal configuration of anchors and pile wall
