补充近期大量试验资料后提出了粒料反滤层的设计准则。区别了作用在粒料反滤层结构的稳定流和循环流,这些水流平行或垂直细粒被保护土和粗粒反滤层的交界面。对这些水流情况组合也进行了研究。给出了反滤层作用的物理解释,收集一些有关试验的新成果:(1)上覆荷载对粒料反滤层性能的影响;(2)级配反滤料的内部稳定性。
After adding a large number of recent experimental data put forward the design criteria of the particle filter layer. Distinguishes the steady flow and the recycle flow acting on the structure of the particulate anti-filtration layer which are parallel or perpendicular to the interface of the fine-grained soil and the coarse-grained anti-filtration layer. A study of these water flow combinations has also been conducted. The physical explanation of the function of the filter layer is given, and some new results about the test are collected: (1) the influence of the overlying load on the performance of the particle filter layer; and (2) the internal stability of the filter material with gradation.
