Propagation Velocities of Elastic Waves in Saturated Soils

摘要: 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.

Abstract: Bused on the wave equations established by the authors, the characteristics of propagation velocities of elastic vaves in saturated soils arc analyzed and verified by ultrasonic test in laboratory and seismic survey in the field. The results provide theoretical basis for the determination of physical and mechanical parameters of saturated soils using propagation velocities of elastic waves, especially P-wave velocity.
