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

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.
