摘　　要：裂隙岩体结构复杂,岩体的渗流特性与应力环境存在着密切关系,渗流场对应力场同样也存在影响。在国内外相关研究的基础上,系统地归纳了岩体渗流-应力耦合裂隙网络模型的建立思路、裂隙处理方法等。提出地下岩体中裂隙网络是无法完全可观测的,实际得到的数据并不充分,在随机模拟时,如何选择反映实际岩体特性的随机分布还有待进一步研究,在耦合模型中如何更真实地表征裂隙随应力的变化关系也需进一步研究。The structure of fracture rock is complicated,but there is a close relationship between the rock seepage characteristics and stress environment,and the seepage field also plays an important role in the paper field.On the basis of the achievements of correlated studies both at home and abroad,the paper reviewed the network model of the seepage-stress coupling in fracture rock systematically,such as the model ideas,the treatment of fracture generation and so on.It proposes that it＇s disabled to observe the fracture network fully in the underground rock,and the actual data is imperfective.How to choose the random distribution which reflects the actual characteristics of the rock and how to represent the more realistic relationship of fracture and stress in the coupling model remain to be further elucidated.
