摘要：基于多孔介质理论 ,在小变形、固相骨架和流相不可压的假定下 ,建立了流体饱和多孔介质拟静态、动力响应的若干变分原理 .本文的变分原理之一可容易退化为
Based on the theory of porous media,several variational principles for the initial boundary value problems of dynamical and quasi-static responses of fluid-saturated elastic porous media are developed by assuming infinitesimal deformation and incompressible constitutes of solid and fluid phase. As a special case,Gurtin variational principle can be easily derived from one of these principles.
