摘　　要：基于高应变动测技术原理,在预应力混凝土管桩工程的静载试验桩中进行高应变动力检测,对采集的有效力和速度信号进行实测曲线拟合法计算,得出PHC桩周土阻力分布数据,为优化工程桩的选型与布置设计提供参考。The distribution of soil resistance around the pile shaft is one of the key parameters in the design of pile foundation engineering.Therefore,accurately obtaining the pile-side soil resistance parameters is a crucial factor in optimizing the selection and layout design of pile foundations.This paper discussed the principle of the high strain dynamic measurement technique.By conducting high strain dynamic tests on static load test piles in prestressed concrete pipe pile projects,the collected force and velocity signals are analyzed using the curve fitting method.The distribution data of soil resistance in each soil layer around the pipe piles are calculated,providing more scientifically and reasonably soil resistance parameters for optimizing the selection and layout design of engineering piles.
