摘　　要：为研究剪切波在细粒土中的传播特性,针对不同含水率的粘土试件进行了室内重型击实试验,并测其剪切波速值。大量试验结果表明:剪切波速与干密度和含水率有很好的相关性,同时分析了干密度和孔隙水对剪切波速的影响机理。研究结果为剪切波速测试分析技术评价压实质量提供参考。To study the character of shear-wave variation law of plain soil.The indoor compaction experiment was carried to test the clay under different water content. The test result indicated that the water content and dry density are related strongly to the shear wave velocity. Then analyzed the effect mechanism on the shear-wave velocity by two factors. This conclusion is valuable in compaction degree evaluation by the shear--wave velocity.
