Abstract
Seepage and stress field interaction is one of important characteristics of rock mass which can not be ignored. Rock mass seepage and stress field coupling has become one of the hot and difficult problems in rock mechanics, and also a scientific problem in practical engineering which need to solve. In this paper, based on a Water Resources and Hydropower Engineering to establish the geotechnical model, according to the discrete fracture network, the equivalent continuous medium mathematical model of seepage and stress field coupling was constructed, the efficient numerical methods and computer program for solving seepage and stress field coupling were developed, the rock mass deformation and failure under seepage and stress coupling were conducted the quantitative analysis, which provide a new technical ways and means for scientific predicting the stability of Water Resources and Hydropower Engineering. The computation results show that the seepage and stress field coupling effect should be considered when analyzing rock mass deformation.
