Research of Hybrid Analysis Model for Coupled Seepage and Stress in Rock Mass of Equivalent Continuum

摘要

By the linkage between the seepage coefficient,porosity and stress,the hybrid analysis modelfor coupled seepage and stress field in rock mass of equivalent continuum is established. The FEMnumefical method is used to analyze the example when the seepage field is unsteady. The computationresults show that the coupled action makes the stress components in rock mass increase in differentdegree,especially σx increases greatly. It is very significant for the practical engineering design.
