SASW法在液化地基加固处理中的应用研究

Application of SASW in Liquefiable Ground Improvement

介绍了SASW法的基本原理与测试方法 ,并将该方法用来评判液化地基的液化势 ,通过试验对比 ,采用SASW法对强夯法和挤密桩法加固液化地基的效果进行了评价 。

This paper presents the SASW method to evaluate the soil liquefiable and improvement techniques. The authors have done detail field tests in the Lianxu highway engineering of Jiangsu province,where the dynamic compaction and dry vibro gravel pile are used to improve the liquefaction soil. According to the tests,SASW method is confirmed to be an effective and feasible tool for the evaluation of the soil improvement and the relationship between the the velocity V s and the SPT blow number N is put forward.
