单层支点排桩在深基坑支护中的应用

Application of Soldier Piles with a Single Fulcrum in the Deep Foundation Pit

介绍了平均深度达16m的基坑工程实例。在分析基坑周边环境条件、工程地质条件的基础上,对三种可选的支护方案进行了比较,最终选择了单排锚索的桩锚支护体系进行支护。监测结果显示基坑变形均满足要求。该支护方法不但能保证基坑安全,而且可节约成本、缩短工期,可为类似工程提供借鉴。

An engineering example of a deep foundation pit, which average depth is 16.0m, is introduced in this paper. Based on the analysis of the surroundings around foundation pit and the engineering geological conditions, three optional methods to retain and protect the foundation pit were compared, finally the soldier piles system with a single row of anchor was chosed as the supporting system for the pit. Monitoring result shows that foundation deformations meet all the requirements. The chosen method can not only ensure the safety of the foundation pit, but also cut the cost and shorten the project duration, it can provide reference for similar projects.
