复合土钉支护结构中钢管桩受力及变形实测分析

Measurement and analysis of earth pressure on the steal pipe pile and its deformation in a composite soil-nailing supporting structure

为了深入研究复合土钉支护结构中钢管桩的工作性能 ,以广州珠江新城E1- 1地块项目基坑为例 ,通过对该基坑复合土钉支护结构中钢管桩侧土压力和钢管表面应变的现场监测 。

For the further study on the working behavior of steal pipe pile in composite soil nailing supporting structure,this paper analyzes the pressure acting on the pile and its deformation based on the observation data of earth pressure on the steal pipe pile and the surface strain of the pile in a composite soil nailing supporting foundation pit in E1 1 area of Xincheng,Guangzhou.
