| 摘要: |
| 为适应网状和层状渗透结构，根据多边形裂隙网络理论．确立了裂隙网络生成的原理和方法，系统地推导了在渗流和应力耦合作用下裂隙岩体渗流模型。并结合拉西瓦水电站坝区岩体裂隙构造的特征，进行了渗流计算和分析；还与连续介质和裂隙网络渗流模型进行了计算比较。 |

| Abstract: |
| In this paper,a new model is completely derived on seepage through fissured rock mass under the coupled action of seepage and stress.To suit the needs of netted and stratified structures,principle and methods for producing fissured network are determined for the computation of seepage according to polygon fissured network theory.In the light of tectonic characteristics of rock fracture in the Laxiwa dam area,computation and analysis of seepage are fully conducted. Compared with porous media seepage model and fissured network seepage model,the present model shows its superiority. |
