| 摘 要： | 采用自行研制的直剪仪和斜板仪研究了3种粗糙程度的HDPE(高密度聚乙烯)膜分别与砂土、土工布及土工复合材料之间的界面摩擦特性,进行了高垂直应力的直剪试验和低垂直应力下的斜板试验.通过对试验数据进行分析比较,认识了一些HDPE膜界面摩擦特性的变化规律及其影响因素,并对直剪试验结果与斜板试验结果之间的差异进行了初步的研究.

| Abstract: | The interface shear strength was studied using direct shear machine with high stress and tilt table device with low stress. Here the interfaces between three different types of HDPE (high density polyethylene) geomembranes and sand, geotextile and geocomposite were considered. Tests were performed with interface scale of 200 mm 200 mm. Through the analyses of test results, some frictional characteristics of HDPE geomembrane interface were provided; and the comparison between direct shear test and tilt table test was made. |
