| 摘 要： | 该文通过运用ANSYS有限元分析软件对软土路基土工格栅加筋的作用机理进行了数值模拟，研究了土工格栅加筋对软土地基应力场和位移场分布的影响。从计算结果分析可知，土工格栅堤底加筋对约束浅部地基土水平位移有显著作用，使最大水平位移点移向地基深处，使堤趾水平位移大幅减小，同时对竖向沉降有一定的均衡作用，加筋增强了路堤的整体性和稳定性，对地基承载力的提高也有一定作用。特别是加筋前后地表最大水平位移点的移位，对路堤填筑施工监测有一定借鉴意义。

| Abstract: | Through applying ANSYS finite element analysis software,the article carries out the numerical simulation of the action mechanism of the soft soil roadbed earth grid stiffening,and studies the influence of the earth grid stiffening on the distribution of the stress field and displacement field of soft soil subgrade.From the analysis of the calculation result,it can be known that the stiffening at the bed of embankment of earth grid has the obvious action on restraining the horizontal displacement of the shal... |
