چکیده
Abstract Dams are important structures for the development and utilization of water resources, dam stability is significantly affected by filter layer. In this paper, eight groups combination seepage tests impermeable materials were conducted. The effects variations in grade, relative density, thickness on resistance performance assessed. test results showed that: material grade affect resistance. critical hydraulic gradient permeability coefficient decrease 34% with increasing soil coarseness within design envelope. failure specimen decreased 17 20%, when density from 0.7 to 0.5, respectively. Therefore, actual engineering applications, dry or should be strictly controlled during filling. Increasing benefits seepage. effect changes particle composition characteristics can expressed controlling constriction size.
