| 摘 要： | 采用室内试验方法对路基土石混合料的渗透特性进行试验研究后,得出以下结论:(1)在水力坡降小于3~5时,土石混合料的渗流遵守达西定律;(2)影响土石混合料渗透性的主要因素是土石混合料颗粒的不同堆积方式及所形成的孔隙系统的不同几何形状等物理因素;(3)土石混合料的细颗土含量与渗透系数之间存在负指数关系。

| Abstract: | Indoor tests were conducted for the permeability of subgrade earth-rock mixture, based on which the following conclusions were summarized： （1） when the hydraulic gradient slope is less than 3- 5, the seepage flow of earth-rock mixture conforms to Darey＇s Law; （2） permeability of earth-rock mixture is mainly affected by grain aceumulating mode and geometry shape of voids; （3） there exists negative exponent relationship between fine-grained soil content and permeability coefficient of mixture. |
