工程桩静载试验确定PHC管桩承载力

On Ascertaining the Design Plan of the Prestressed High-strength Concrete Pile Foundation by the Static Test of an Engineering Pile

以工程实例介绍静压管桩基础的设计承载力取值,采用先施工工程桩进行静载试验,以其结果反算单桩竖向承载力,结合桩的入土长度等给出应用于工程实际的单桩竖向承载力设计值(R)的方法,供同行借鉴。

The paper presents the method of calculating the design values of vertical bearing capacity of a pile on the base of the bearing capacity of static-pressure piles. The design R values are computed by the static test of an engineering pile at first, the bearing capacity of a single pile gained by the inverse computation of the results from the about-mentioned static test and the embedment length of a pile.
