摘要
考虑到多孔介质渗透率随孔隙变化的特点， 研究二维应力场下承压地层中渗流的液固耦合问题， 提出了解耦方法； 并求出耦合条件下的孔隙压力与介质应力的解析解。计算表明， 耦合效应不容忽略。
Considening the perm eability varying w ith porosity, the liquid-solid coupled problem of the flow in confined strata subjected to tw o-dim ensional in-situ stresses is discussed. First, a decoupled m ethod is proposed, then the solution for the coupled distribution ofpore pressure and stress field is obtained analyti- cally. The com putation ofthe cases show s that the coupled effectcan not be ignored.
