摘　　要：通过对单个铆接型聚酯(Polyester,PET)土工格室加筋土试样开展定速压缩试验,探究土工格室的加筋效果,分析土工格室应用时在土体介质中发挥其侧向约束性能的机理和条带宽度、节点距离对土工格室侧向约束性能的影响。结果表明:土体中的土工格室具备显著的加筋加固效果,侧向约束作用大小由节点剥离强度控制,与条带宽度成反比,与节点距离成正比。A fixed-rate compression test was carried out on a single riveted Polyester(PET)geocell reinforced soil sample to explore the reinforcement effect of geocell,analyze the mechanism of exerting its lateral restraint performance in the soil medium,and the influence of strip width and node distance on the lateral restraint performance of geocell.The results show that the geocell in the soil have a remarkable reinforcement effect,and the lateral restraint is controlled by the stripping strength of the joints,and is inversely proportional to the strip width and proportional to the distance of the joints.
