摘要: 利用修正项来修正Brandt多孔隙颗粒介质弹性理论中的体积模量表达式,使其与BiotGeertsma理论的结果一致起来。提出了计算骨架波速的新方法,探讨了一些物理参数对波速的影响。Abstract: The Brandt’s elastic theory for porous granular media is modified by a term in that its volume modulus is identical to that of BiotGeertsma’s theory. A new way to calculate the skeleton elastic wave velocity is suggested. Some effect of physical parameters on elastic wave velocity are discussed.
