SASW法在粉土液化判别中的应用

APPLICATION OF SASW IN JUDGING SILTY SOIL LIQUEFACTION

文章介绍了面波法 (SASW法 )的基本原理与测试方法 ,并将该方法用于判别黄河三角洲饱和粉土的液化势。通过标准贯入试验结果与瑞雷波法判别结果的对比 ,说明以剪切波速为土性指标的液化判别方法是一个很有前景的方法 ,但由于资料太少 ,建议继续收集液化调查资料 ,以发展出一个有充分根据的液化判别方法。

In this paper the principle of SASW method is introduced,and is also used in judging the saturated silty soil liquefaction of the Yellow river delta. It can be seen from the contrast between the results of SPT & SASW method that the SASW method is a promising one. However,due to lack of relevant data,a liquefaction-judging method should be put forth on adequate basis with the succeeding collection of investigation into liquefaction.
