土工格栅改善路基差异沉降效果分析

Effect Analysis of Geogrid on Improving Differential Settlement of Roadbed

为了深入研究土工格栅对改善路基差异沉降的作用,采用有限元方法,分析了路基加宽过程中不同的土工格栅铺筑位置、填土高度、差异沉降下,路基沉降、路基侧向位移及土工格栅应力的变化规律。

In order to study the role of geogrid in improving the differential settlement of roadbed,the finite element method is applied to analyze the changes of roadbed settlement,lateral displacement of roadbed and stress of geogrid under different geogrid laying position,filling height and differential settlement in the process of roadbed widening.
