摘要：在基坑深度较大的基坑支护中，采用了支护桩的设计方案，当支护桩的设计埋置深度不能满足设计要求时，会造成围护桩的倾覆及土坡的失稳。在通过有限放坡、沉井及中心岛相结合的设计和施工处理方案措施，达到了工程的要求效果。通过这样的处理措施，为基坑支护工程提供了有力的设计及施工依据。

Abstract： The design of Retaining Pile was used in deep foundation pit supporting. When the depth of Retaining Pile cannot meet the requirement of the design, the fall of the guard stake and the instability of the slope will take place. Measures combined by limited slope,open caissons and certre island were taken in the design and the construction treatment,which reached the engineering requirement.Useful reference in design and construction was provided for the foundation pit supporting project.
