本文对采用土工格栅加筋软基路堤的效果进行了有限元分析。计算结果表明,土工格栅对减小软基路堤位移和降低土体应力水平以及消除路堤不均匀沉降都有明显效果。本文还分析了土工格栅的埋设位置对路堤位移以及应力水平的影响,可供工程设计参考。

The finite element analysis of an embankment with a soft subgrade reinforced with geogrids is conducted in this paper. The calculation results show that geogrids have brought an obvious effects in reducing the displacement of a soft subgrade and the stress level of soil mass ,and eliminating the nonuniform settlement of embankment. The influence caused by the position of the embedded geogrids on the displacement and stress level of embankment is also analyzed herein.
