渗透性增强 meaning in Chinese
enhancement of permeability
Examples
- Erosion damage decreases rock load area , after defining damage variable , the damage stress in rock can be calculated by the method bring forward by lemaitre conveniently . for surrounding rock of a deep buried tunnel under the condition of drained , its seepage character is not only controlled by the high stress in rock , but also influenced by the development of erosion damage . in the whole course of rock " s deformation and failure , its seepage character decreases with the increment of stress in elastic stage , while " increases with the development of failure
岩样中全应力?应变三轴渗透试验过程中的典型表现为随着应力的增加，岩体内的空隙和裂纹受载闭合，渗透性降低，应力达到一定阈西南交通大学鹰士研究生学位论文第11页值后，岩体内部裂纹发生扩展和归并，渗透性增强；同样，地下水的动、静压力作用对裂纹的扩展和归并也起着促进作用。
