本研究的目的是评估静态 土-土工膜界面的动态强度 典型衬垫系统中的土工织物界面。这 目标将通过执行广泛的 各种内衬界面的扭转环剪切试验。 将使用环形剪切仪代替直接剪切仪。 剪切或拉出装置 单向剪切变形,恒定的交叉变形, 试验过程中的截面积,较薄的土样 允许更快的排水和残余强度, 更好地符合现场案例历史。
英文摘要
The objective of this research is to evaluate the static and dynamic interface strengths of the soil-geomembrane- geotextile interfaces found in typical liner systems. This objective will be accomplished by performing extensive torsional ring shear tests on the various liner interfaces. A ring shear apparatus will be used instead of a direct shear or pullout apparatus to allow for large continuous shear deformation in one direction, constant cross- sectional area during the test, thinner soil specimens permitting faster drainage and a residual strength in better agreement with field case histories.
