| 摘 要： | 针对互层状裂隙岩体中的渗流问题,总结了互层状裂隙岩体中的层面裂隙和构造裂隙发育规律,提出了一种互层状岩体中裂隙网络生成方法并基于双重介质饱和一非饱和渗流模型分析了软岩中存在和不存在切层裂隙两种情况下自由面渗流问题,讨论了层面裂隙、层问裂隙和切层裂隙隙宽对自由面的影响.结果表明,在互层状裂隙岩体有自由面渗流中可能出现多层自由面的现象,取决于层间、切层及层面裂隙隙宽的组合. |

| Abstract: | For the seepage problems in inter-bed layered fractured rock masses,the development rules of bed fractures and tectonic fractures in inter-bed layered rock masses are studied,and a fracture network generation method is put forward,and then the seepage problems with free surface is analyzed with double medium model with considering the unbounded fracture or not,at last the free surface variation caused by the varying aperture of bed fracture,bounded fracture and unbounded fracture are discussed.The analysis ... |
| Keywords: | inter-bed layered rock masses double medium model free surface |
