摘　　要：以单条平直裂隙中的水流运动规律和裂隙网络渗流模型为基础,介绍了裂隙岩体渗流场与应力场耦合非线性分析的基本原理以及两场耦合的数学模型,并说明了耦合计算方法及步骤,运用算例,通过对比分析耦合及非耦合两种情况下的渗流场等值线图,说明了在渗流场必须考虑水-岩耦合作用。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.
