土工格栅、土工格室加筋垫层对软土地基沉降控制效果的有限元分析

A Finite Element Analysis of Controlling Effect of Geogrid and Geogrid Cell with Reinforced Bed Course on Soft Ground Settlement

结合秦沈客运专线现场测试及室内模型试验的结果 ,利用有限元法 ,分析 1层土工格栅、2层土工格栅和 1层土工格室加筋垫层对软土地基变形的控制效果 ,比较现场试验与室内模型试验中加筋效果的差异。

Based on result of site testing and indoor model experiment, a finite element analysis was made of effect on controlling of soft ground deformation using one\|level geogrid, two\|level geogrid, and one\|level geogrid cell plus reinforced bed course. A comparison was made of differences between site testing and indoor experiment.
