Design of Shoring System for a Deep Foundation Pit Excavation

Underground Construction and Ground Movement, 2006
This paper involves a foundation pit about 10.0 m in depth. The main problems in choosing a supporting system for excavation are difficult geological conditions and pipelines around the pit. Pile-anchor structures (bored piles and pre-stressed anchors) were used as the shoring system in the east, the south and a part of the west of the foundation pit ...

A Case History of the Excavation of Deep Foundation Pit Adjacent to Railway

Tunnel Management, Emerging Technologies, and Innovation, 2011
Minzhi station foundation pit in Shenzhen subway is adjacent to Pingnan railway. There is obvious unsymmetrical loading above the pit, and the pit is affected by the dynamic load from train. Therefore, the impact of pit excavation on the railway and the safety of the pit itself must be paid close attention to. The main technical measures adopted in the
