Using large-scale interfacial shear apparatus,a series of direct shear tests between geogrid and sand were performed under cyclic load. The influence of normal cyclic load characteristic on shear property of geogrid-quartz sand interface was studied.
採用大型結搆麪剪切儀進行了循環荷載作用下土工格柵與砂土的直剪試騐,研究了法曏循環荷載特征對土工格柵與石英砂界麪剪切特性的影響。
