| 摘 要： | 人们对土工合成材料加筋在海堤软基处理中的作用与材料选用尚存在明显意见分歧，从而限制了它恰当地应用。通过某一工程实例，数值分析了筋材在包括极限稳定等各种工况下的受力性状及对提高海堤抗滑稳定性的贡献。利用改装后的位移计，对土工格栅应变进行了原位测试。根据数值分析和原位测试成果，探讨了海堤筋材的选用及其设计参数的选取，得到了海堤筋材应首选单向拉伸土工格栅、选用时应同时规定极限延伸率上下限等一些有益的结论

| Abstract: | There is divergence of opinions on the effect of geosynthetic reinforcement and the selection of suitable geosynthetic materials;it is a constraint for its appropriate application.This paper investigates the mechanical behavior and the contribution of reinforced materials with an reclamation engineering example in Pinghu,Zhejiang province.Besides,in-situ test is made using improved displacement gauge.Based on the numerical analysis and in-situ test,further discussion is made on the type and the correspondin... |
