土工格栅加筋垫层控制地基沉降的试验研究

Study on Settlement Control by Geosynthetic Reinforcement

针对杭甬高速公路软土路基,通过室内模型试验研究和有限元计算,分别对采用三种不同的土工格栅对控制地基沉降效果进行对比分析,探讨了高速公路路基垫层土工合成材料的优选和加筋机理,同时指出了部分国产土工合成材料产品的不足.

This paper adopts model test and finite element method to study the functions of the three kinds of reinforcement layers to control the settlement of soft soil ground, The research suggests that three kinds of geogrids are effective to control the settlement of soft soil ground and glass fiber geogrid＇s reinforcement effect is best. These conclusions can be applied to choose reinforcement layer＇s geosynthetic and study the reinforcement theory. This paper presents the shortcomings of geosynthetics made in China.
