摘要 裂隙岩体非饱和渗流和流固耦合是普遍存在的现象,利用双重孔隙介质模型,在多孔介质弹性理论和广义有效应力的基础上,给出了双重孔隙介质非饱和流固耦合方程的数学推导,经过离散化后可以用于数值计算,最后提出了一些需要进一步解决的问题. The unsaturated seepage and the fluid-solids coupling in fracture-pore rock are ubiquitous phenomena.Based on the elastic theory of porous media and generalized effective stress concept,the governing equations of unsaturated fluid-solid coupling in deformable dual porosity media are derived according to dual porosity media model,and they can be used for numerical calculation after discretization.Finally,some problems to be further studied on the research in this paper are presented.
