摘　　要：分析岩土的动力性质时可以参考地震波速,对场地中的原位地震波速和其他性能进行研究,根据实验结果分析岩土性能。与压缩波相比,剪切波受到了更多的关注,其在岩土液化势的判别中具有更大的优势和价值。文章对剪切波的作用和获取方法进行分析,结合工程实例进行研究,探讨地震剪切波判别岩土液化势的效果,根据工程测试数据,将工程场地中的砂土判别为不液化。When analyzing the dynamic properties of rock and soil,we can refer to the seismic wave velocity,study the in-situ seismic wave velocity and other properties in the site,and analyze the rock and soil properties according to the experimental results.Compared with compression wave,shear wave has received more attention,which has more advantages and value in the identification of liquefaction potential of rock and soil.The paper analyzes the action and acquisition method of shear wave,and studies the effect of seismic shear wave on identifying the liquefaction potential of rock and soil in combination with engineering examples.According to the engineering test data,the sand in the engineering site is identified as non liquefaction.
