| 摘 要： | 为了研究在垂直荷载作用下高压旋喷桩复合地基的性状及其工作机理,通过试验等方法说明了高压旋喷桩的力学性质.在垂直荷载作用下,桩、土都可以承担上部荷载作用,进而能大幅度提高复合地基承载力,改变了桩传递轴向应力的特征,减小了基础底面的压力等.通过研究,从理论上对高压旋喷桩复合地基的基本特性有了更清楚的了解.

| Abstract: | In order to study the character and the action mechanism of the high pressure jet grouting pile composite foundation induced by vertical load, the mechanics character of the high pressure jet grouting pile is explained using experiments.Some results are as follows∶ under the action of vertical load,piles and soils are able to support upper loads,this improving the bear capacity of composite foundation a lot;changing the character of the pile during transferring the vertical stress,reducing compressive stress under foundation.It is likely to clearly understand the basic actions of the high pressure jet grouting pile composite foundation by summarizing the theory of the high pressure jet grouting pile composite foundation systematically. |
