“剪力钳”支护结构在基坑支护中的应用分析

Application Analysis of"Shear Clamp"Supporting Structure in Foundation Pit Supporting

在常用的单排悬臂桩支护结构基础上,进行“剪力钳”支护结构设计,开展PVC材料弹性模量测定、基坑试验模拟土体测定和基坑试验槽尺寸测定,通过单排悬臂桩试验对照组和“剪力钳”试验组的基坑开挖模拟和有关弯矩的数值分析,为“剪力钳”支护结构应用提供数据支撑。

Based on the common single-row cantilever pile supporting structure,the"shear clamp"supporting structure is designed.The elastic modulus of PVC material,the simulated soil mass of foundation pit test and the size of foundation pit test slot were measured.The simulation of foundation pit excavation and the numerical analysis of bending moment of the single row cantilever pile test group and the"shear clamp"test group were carried out to provide data support for the application of"shear clamp"supporting structure.
