摘　　要：斜板仪主要构件为一端铰接在一起的两块平板,试验中顶升上平板自由端,直到试块在斜板上滑动,并读出斜板倾角。试验可以较好地模拟城市卫生填埋场斜坡上衬垫系统的实际状况,测量各材料之间的摩擦特性。笔者研制了简便的斜板仪,测量了3种粗糙度的HDPE(高密度聚乙烯)膜与砂土﹑土工复合材料﹑有纺土工布之间的摩擦特性,得到一些有益的结论。The essential components of tilt table device were two plates hinged together at one end. The upper plate, on which test sample was put, was continuously lifted at the free end till sample slided. The inclination of the plate was recorded. This device could measure interface frictional properties between components of lining system factually realizing the field condition of slope of landfill where normal stress was low. A simple tilt table to measure the frictional characteristics between three different HDPE （high density polyethylene） geomembranes and sand, geocomposite and woven geotextile, and the test results were presented.
