| 摘 要： | 当路堤进行加宽改造时，多采用土工格栅以增强路堤边坡的安全稳定性。基于有限元理论的强度折减系数法，从加筋刚度、加筋长度、加筋布置方式、筋土界面作用四个方面考虑，有助于有效地分析土工格栅对路堤加宽各阶段安全稳定性的影响。

| Abstract: | Geogrid is always used to improve the safety and stability of slope when road base is widened. Strength reduction method based on finite element theory can be used to analyze the effect of safety and stability for each phase of slope widening from four aspects of geogrid, such as stiffness,length, layout manner and soil-structure interaction. |
