| 摘 要： | 文章基于三维拉格朗日有限差分的原理,用拟静力法和动力法来分析土工格栅填土边坡的动力特性和抗震性能。研究结果表明土工格栅能很好地提高填土体的强度和抗震性能;动力法计算结果比拟静立法计算结果更为安全,且只有动力法才能分析出填土边坡失稳的主因。

| Abstract: | Based on the principle of three-dimensional Lagrangian finite difference,the article used the quasi-static method and dynamic method to analyze the dynamic characteristics and seismic performance of geogrid filling slope.The study results showed that the geogrid can well improve the strength and seismic performance of filling soil body;the calculation results of dynamic method is much safer than the calculation results of quasi-static method,and only the dynamic method can analyze the main cause of filling-slope instability. |
