摘要
通过天津地区30根预应力管桩的水平静载荷试桩结果,分析了天津地区预应力管桩水平承载力特征值和对应的水平位移值,并对JGJ 94-2008建筑桩基技术规范提供的预应力管桩水平承载力估算公式中桩顶允许水平位移值在天津地区的取值进行了总结,以供参考。
Base on the result of horizontally loading test of 30 prestressed concrete pipe piles in Tianjin,the paper analyzes the characteristic val-ue of horizontal bearing capacity and the horizontal displacement values of prestressed concrete pipe pile in Tianjin,and summarized the allowable value of the horizontal displacement of pile-top in the formula in Technical Code for Building Pile Foundations（JGJ 94-2008）,so as to be refer-ence.
