摘要
蠕变是土工合成材料应用于永久性加筋土结构中的重要特性。较详细地介绍了蠕变的机理和影响因素、试验仪器、操作步骤和试验成果的整理方法,以及为减短试验持续时间而推荐的时温叠加法和分级等温法,比较了不同规范的要求,同时还简要介绍了土工合成材料的动力蠕变试验和土工泡沫及土工合成材料粘土垫层的蠕变试验以及铺设破坏与蠕变结合的试验,给出了对蠕变研究的一些建议。
Creep is an important property of geosynthetics for its application in any permanent reinforced structures. The principles and effect factors of creep, testing equipments and operating procedures, time-temperature superposition and stepped isothermal method for decreasing the lasting time of creep test and a comparison of different cords are presented. Meanwhile, dynamic creep test, creep tests of geoform and geosynthetics clay liners and combined analysis of installation damage and creep are briefly introduced. Finally, some suggestions about research on creep of geosynthetics are given.
