摘　　要：下文通过系统的试验研究,探讨了不同材质、结构类型以及环境等因素对土工格栅加筋材料循环剪切性能的影响。实验结果表明,土工格栅材质、结构类型、预应力、环境条件等因素显著影响加筋材料的循环剪切性能。聚酯(PET)土工格栅的循环剪切强度比聚丙烯(PP)材料更高,且在循环荷载作用下表现出较好的耐久性。双向土工格栅的加筋效果优于单向格栅,能有效延缓强度衰退。本研究为土工格栅加筋材料的设计优化及实际工程应用提供了宝贵的理论依据和实践指导。Through systematic experimental research,this article explores the effects of different materials,structural types,and environmental factors on the cyclic shear performance of geogrid reinforced materials.The experimental results indicate that factors such as geogrid material,structural type,prestress,and environmental conditions significantly affect the cyclic shear performance of reinforced materials.The cyclic shear strength of polyester(PET)geogrid is higher than that of polypropylene(PP)material,and it exhibits better durability under cyclic loading.The reinforcement effect of bidirectional geogrid is better than that of unidirectional grid,which can effectively delay the strength degradation.This study provides valuable theoretical basis and practical guidance for the design optimization and practical engineering application of geogrid reinforcement materials.
