摘　　要：采用自制斜板仪,模拟低应力条件下边坡衬垫系统受力状态,测量了GCL与不同下垫层接触面的摩擦特性参数。试验结果表明,下垫层土体含水率、密实程度及GCL水化条件等因素对接触面摩擦特性均产生一定影响。通过分析试验结果,对实际工程中边坡衬垫系统的设计和施工提出建议。Frictional parameters of interface for GCL-different underlayer were measured by using tilting table device,which could simulate stress state of slope liner system in low stress condition.Test results indicated that frictional behavior was influenced by water ratio,compaction rate of soil underlayer,and hydration condition of GCL.Beneficial proposals were given to design and construction of slope liner system in practical project according to analyzing test results.
