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。
There is a clear divergence of views on the role of geosynthetics in the soft foundation treatment of seawalls and their material selection, thus limiting its proper application. Through a project example, numerical analysis of the mechanical properties of tendons under various working conditions, including ultimate stability, and their contribution to improving the stability of the anti-sliding of seawalls. Using the modified displacement meter, the geogrid strain was tested in situ. According to the numerical analysis and in-situ test results, the selection of the seawall reinforcement material and the selection of its design parameters are discussed. It is concluded that the unidirectional tensile geogrid should be the first choice for the seawall reinforcement. The upper and lower limits of ultimate elongation And some other useful conclusions.
