| 摘 要： | 本文将液型介质向松散的沙质沉积物中延拓，获得了松散沙质沉积物中的有效密度表达式，利用该表达式计算了松散的沙质沉积物表面上的平面声波的反射系数的模，并与实验数据进行比较，理论与实验相符合。

| Abstract: | In this paper, through extension from liquid medium to loose sandy sediment, the expression of the effective density in loose sandy sediment was obtained. Utilizing this expression, we calculated the module of reflection coefficient of plane wave on the surface of loose sandy sediment. The theoretical results are in good agreement with the experimental data. |
