振动沉管碎石挤密桩加固软土地基

The Method of Vibrating Sinking Pipe and Gravel to Dense Pile for Stabilizing the Soft Soil Foundation

对特殊地质条件下的盐渍土地基采取何种技术措施来解决三方面的技术难题,一是解决提高地基承载力,二是解决地基土的高压缩性及液化带来的基础沉降问题,三是解决土层中的高盐含量对混凝土和钢材的高强度腐蚀问题。本文采用振动沉管碎石挤密桩的方法对地基土进行了加固,取得了良好的效果。

The technical measures should be taken to solve the technical problems in three aspects for saline soil foundation.First improving the Bearing capacity of the foundation,Second,solving the problem of foundation settlement on account of the high compressibility and liquefaction of foundation.Third,solving the problem of the high corrosion to concrete and steel arised from the high salinity in soil.In this Text,the method of vibrating sinking pipe and gravel to dende pile for stabilizing the foundation is applied and good effect achived.
