摘要
强夯法处理湿陷性黄土,提高黄土的地基承载力是一个技术成熟、工艺简单、造价较低、施工速度快的基处理方法,其前提是地基土要具备适宜的含水率,才能达到较好的夯实效果[1]。当地基土含水率较低时,增湿成为配合强夯作业必不可少的前期工作,砂井注水增湿法在湿陷性黄土地区有较好的效果,本文以实际工程为依托,从方案设计、施工工艺,再到取样检测及成果分析,详细介绍了该工法的应用及良好的增湿效果。
Dynamic compaction method which has been used for foundation treatment of collapsible loess, can improve the foundation bearing capacity of loess. It is a mature technology with simple process, low cost and fast construction period. The premise is that the foundation soil should have appropriate moisture content, which can achieve good compaction effect. When moisture content of the foundation soil is low, the sand drain water flooding humidification method has good effect in collapsible loess area Based on the actual project, from design,construction technology to the testing samples and the analysis of the results, this thesis gives a detailed introduction of the application of this method and its good damping effect.
