1) Percolation leakage crack
逾渗漏风裂隙
2) percolation crack
逾渗裂隙
1.
Moreover, the producing and opening situation of percolation crack at the fault area in the 4308 caving roadway in Dong-tan coal mine is intro-duced.
探讨了煤层巷道巷帮煤体及采空区冒落煤体逾渗漏风裂隙的分形特征,并对东滩煤矿43_上08工作面煤层巷道构造位置逾渗裂隙的形成与扩展情况进行了分析和讨论。
3) seepage in karst fissure type
岩溶裂隙式渗漏
5) leaky fracture
渗漏裂缝
1.
Mechanism of leaky fracture formation in water storaged dam foundation and dam body has been calculated theoretically and compared from the point of view of rock and soil mechanics.
从岩土力学的角度对水库蓄水后坝基和坝体形成渗漏裂缝的机理进行了理论计算和对比，结果表明，大高度蓄水静水压产生的附加应力并不是形成渗漏裂缝的主要因素，而一定高度蓄水引起岩土体内孔隙压升高到极限值才是产生破坏性裂缝、形成渗漏的主要原因。
6) fracture seepage
裂隙渗流
1.
During researching the problem of fracture seepage in rock mass with the equivalent continues media model, the abnormal water head phenomenon of some nodes were found by the finite element method.
针对利用等效连续导水介质模型研究岩体裂隙渗流问题时，有限元计算部分结果出现的水头反常现象，经多因素分析，认为渗透张量与渗流区域边界形状之间存在着相互协调的条件，当这种条件被超越时，就会使计算结果出现水头反常现象。
