根据所建立的波动方程分析了饱和土中弹性波的弥散特性,并且用室内超声波和现场地震波试验结果进行验证.本文为由弹性波(尤其是P波)速度测得合理的饱和土物理力学参数提供了理论依据. Based on the established wave equation, the dispersion characteristics of elastic waves in saturated soil are analyzed and verified by indoor ultrasonic and in-situ seismic wave test results. This paper is a reasonable physical and mechanical parameter of saturated soil measured by elastic wave (especially P wave) velocity. Provide a theoretical basis.
