双排桩基坑支护在膨胀土地区的工程应用

Behavior of Cantilever Double Soldier-Piled System for Deep Excavation in Expansive Soils

以成都望江锦园工程为例,介绍了双排桩支护体系在深基坑支护中的应用,基坑侧壁的变形观测结果表明,双排悬臂桩支护能够有效控制基坑水平位移。

The cantilever double soldier-piled supporting system was used for a deep excavation in Wangjiang Garden project in East Chengdu City. The subsurface soil consists of expansive cohesive soils. This paper presents an application of this type of supporting system in the deep excavation. The construction monitoring indicates that the cantilever double soldier-piled system can effectively limit the horizontal displacement during the excavation.
