摘　　要：某临近地铁基坑支护工程,场地分布透水性好以及软弱地层,文章对基坑支护设计及实施中遇到的问题进行分析,提供切实可行的解决方案:单根支撑轴力监测可设置2个监测点,同时根据规定采用自动化监测;不同规范对弹性支点刚度系数规定略有区别,应根据实际情况注意规范的选用;当基坑开挖场地受限,可考虑不留肥槽的贴壁施工方案;箍筋直径较大,弯折成矩形困难时,可调整为两个对扣三角形。This article analyzes the problems encountered in the design and implementation of foundation pit support in a nearby subway foundation pit support project,which has good permeability and weak geological strata.A practical and feasible solution is provided:two monitoring points can be set for single support axial force monitoring,and automatic monitoring can be adopted according to regulations;There are slight differences in the regulations for the stiffness coefficient of elastic supports in different specifications,and attention should be paid to the selection of specifications according to actual situations;When the excavation site of the foundation pit is limited,a wall adhering construction plan without leaving fertilizer slots can be considered;When the diameter of the hoop reinforcement is large and it is difficult to bend it into a rectangle,it can be adjusted to two interlocking triangles.

关 键 词：深基坑支护 基坑监测 箍筋 贴壁施工
