Analysis of Bearing Performance of Large-diameter Cast-in-place Piles Based on Improved Self Balancing Static Load Method
Take the testing of bearing capacity of foundation piles of a high-rise building project as an example,after calculation,an improved self balancing method is adopted to determine the pile top loading capacity.At the same time,internal force testing elements are set at the boundary of the soil layer of the pile body to monitor the axial force of the pile body during the loading process,and then determine whether the bearing capacity of the pile body is fully exerted.The results show that the improved self balancing method effectively solves the need for deep pile foundation bearing capacity detection.The bearing capacity of the pile foundation under ultimate load has been fully utilized,and the aver-age lateral friction value of each soil layer is similar to the geological survey report.The ultimate bearing capacity of a single pile and the design parameters of the pile foundation can meet the requirements of pile foundation design.
