摘要： 介绍了软土地区采用重力式挡墙或土钉墙与桩撑联合支护方式的深基坑支护的工程实例，将此种联合支护方式与单纯的桩撑、重力式挡墙及土钉墙的支护方式进行对比，探讨总结了此种联合支护方式的可行性、适用范围、特点优势等。通过实际工程的实践应用及其现场监测数据成果分析表明此种联合支护是安全、可行的，并具有一定的优势。针对位于软土地区开挖深度在7.0~12.0 m之间的基坑工程，推荐使用重力式挡墙或土钉墙与桩撑联合的支护方式。

Abstract: A case history of the deep excavation in soft soils supported by the combination of gravity retaining wall, soil nail wall and pilestrut is presented in this paper. The paper compares the feasibility, advantages and disadvantages of this combination method with the application of one of the three methods alone in the deep excavation. The construction monitoring data indicated that this method can be successfully used in the deep excavation project in soft soils with an excavation depth between 7 and 10 meters.
