Diaphragm wall deformation behaviors analysis of deep excavation in soft soil metro station

City construction advanced the high-rise buildings and underground space to be built. To develop underground traffic is the inexorable trend to solve the traffic jam. Deep excavation of the metro station in soft soil usually gives rise to many environmental problems, such as slope failure, water burst and building settlements. This article analysis the construction step and techniques based on the factors of soft soil environmental geology and construction conditions. It provides some methods and advices. To secure the nearby buildings and roads by means of foundation reinforcement minishing enclosure wall displacements and use logical construction scheme.
