预制桩竖向极限承载力的时间效应规律研究

摘要

According to the measured results of high strain during different resting periods,the paper sums up the time effect law for the vertical ultimate bearing capacity of precast piles by combining with projects,and indicates the time effect mechanism of saturated clay bearing capacity.%根据不同休止期高应变的实测结果，结合实际工程总结了混凝土预制桩单桩竖向极限承载力的时间效应规律，论述了饱和软粘土承载力时间效应机理。
