It consists of two parts : the first part ( chapter 2 , 3 , 4 , 5 ) studies the characteristic of elastic waves and surface waves in orthotropic fluid - saturated porous media using biot ' s theory which is based on the substitutive model . in the second one ( chapter 6 ) , a new three - dimensional meso - calculating model , which is more coincided with the inner action mechanism of porous media , is proposed . based on this model , the elastic wave propagation in fluid - saturated porous media under longitudinal impacting is discussed
论文主要分为两大部分：第一部分基于替代模型的biot理论，对各向异性介质中平面波以及表面波的传播特性进行了研究；第二部分从细观层次出发，提出了一个更加符合含液饱和多孔介质内部作用机理的三维细观计算模型，并对纵向冲击载荷作用下液饱和多孔介质中弹性波的传播规律进行了讨论。
