【Abstract】 The basic principles of nonlinear analysis of fractured rock mass field and stress field coupling and the mathematical model of coupling of the two fields were presented based on water flow movement rule in single straight fracture and fracture network seepage model.The coupling calculating method and the calculating procedures were introduced.In addition,an example was employed to compare the contour maps of the seepage fields in coupled conditions and in uncoupled conditions.It indicated that the coupling effect of the water-rock mass must be considered when the seepage field played a vital role.更多还原
