摘　　要：静压桩作为一种常见的基础形式,在各类工程中广泛应用,其承载力存在时间效应。论文分析了静压桩承载力的时间效应机制,并通过对工程实例中静压桩试桩、施工及复压等过程中的压桩力进行分析与阻力验算,发现静压桩在施工初期承载力不足,通过一定时间的静置和复压,桩基的承载力显著提高,甚至超过设计要求。特别是时间效应对桩侧阻力的增加作用明显,验证了其对桩基长期稳定性和承载力的积极影响。As a common foundation form,static pressing pile is widely used in all kinds of projects,and its bearing capacity has time effect.This paper analyzes the time effect mechanism of static pile bearing capacity,and through the analysis of pile pressure and resistance checking calculation in the process of static pressure pile test,construction and re-pressure of an engineering project,it is found that the bearing capacity of static pressure pile is insufficient in the initial stage of construction.After a certain period of static and re-pressure,the bearing capacity of pile foundation is significantly increased,even exceeding the design requirements.In particular,the time effect has an obvious effect on the pile side resistance,which verifies its positive influence on the long-term stability and bearing capacity of pile foundation.
