PHC管桩承载力时间效应研究

Study on the time-effectiveness of PHC pipe pile bearing capacity

分析了PHC管桩承载力时效性特征,探讨了考虑时效性的管桩单桩承载力计算方法,通过现场试验,分析了PHC管桩单桩承载力与沉桩间歇时间的关系,建立了考虑时效性的单桩承载力计算公式。

The paper analyzes the time-effectiveness features of PHC pipe pile bearing capacity,and explores single pipe pile bearing capacity calculation method by taking time-effectiveness into consideration. Through site experiment,it analyzes the relationship between single PHC pipe pile bearing capacity and sinking pile intervals,and establishes single pipe pile bearing capacity calculation formula by taking time-effectiveness into consideration.
