摘要
通过在桩身不同部位埋设土压力盒和钢筋应力计等原位测试手段,对相同桩长、相同主桩径的普通直身桩和挤扩多支盘桩进行了对比性试验,分析了两种桩在受力机理上的区别,研究了挤扩多支盘桩的载荷传递机理,以及支盘端阻力、桩身侧摩阻力随着沉降、载荷改变的变化规律,为该桩的进一步推广提供了理论依据。
A field test is carried out on the mechanism of general pile and muff-plate-pile by means of embedding pressure cells and reinforcement stress gauges. It investigates the distinguishing characters of the special pile, including load transmission law, the variation law of tip resistance and lateral resistance with the change of load and settlement, and so on. Thus it provides new academic information to promote the usage of this special pile.
