【摘要】 加筋土技术已在公路、水运、铁道、水利等工程中广泛采用。加筋材料在工程中的蠕变性及耐久性问题一直是人们关注的重要问题。通过对土工格栅的系列变形试验,得出土工格栅长期荷载作用下的变形特征,即变形率与时间呈对数关系,与应力大小呈“S”曲线关系,为加筋土结构设计计算和加筋材料在工程上的应用提供重要参考。更多还原

【Abstract】 Reinforcement soil technology has been widely applied in road,marine,railway and water conservancy projects,creep features and endurance of reinforcement soil material in project structure has long been the focus of engineers.Through series deformation test to geogrid,deformation feature of geogrid under long term load is concluded,i.e.the deformation ratio is in logarithm relationship with time,and in "S" curve relationship with strain.This would provide important reference to reinforcement soil structure design & calculation,application of reinforcement material in projects.更多还原
