桩锚与复合土钉墙支护在深基坑工程中的应用

Application of the Anchored Soldier Pile and Lagging and Soil Nail Walls in a Deep Excavation

根据某基坑工程的岩土条件、开挖深度及周边环境,选择采用桩锚及复合土钉墙进行支护,给出了典型剖面的设计图,并对设计进行了验算,验算结果满足规范要求。分析了基坑支护设计、施工、监测应注意的问题。对类似基坑工程的设计、施工具有借鉴意义。

The selection of the supporting scheme for a deep excavation project is based on the subsurface condition, depth of the proposed excavation, we well as the adjacent environment. A combination of anchored soldier pile ＆ lagging wall with the soil nailed wall was used. The paper presents a typical design section that illustrating the gist of this application. The design checks indicate this predicted performances meet the code requirement. The design, construction and instrumentation aspect of this project are also introduced.
