依托北京地铁十号线二期工程实例,对线路上存在空间交叉关系的四线明挖区间结构的基坑设计进行了介绍,采用钢管内支撑、锚索支护、土钉支护等支护手段,解决了四线区间同时明挖时交叉节点处的基坑处理问题,为今后类似工程基坑设计提供了指导。

Based on the Second Period of the 10th Line of Beijing Subway,the study introduces the foundation pit design at the quadruple-track open trench structure whose route has the spatial crossing relation,introduces the supporting measures for the internal support of the steel pipes,the support of the anchor cable,and the soil nailing support,and solves the problems in the foundation pit treatment at the crossing joint of the quadruple-track Section and the open trench,so as to provide the direction for the foundation pit design of similar projects in future.
