塑料土工格栅加固软基路堤加筋效果的有限元分析

Finite Element Analysis of Reinforced Effect on Soft-groundwork Embankment Reinforced by Plastic Geogrid

通过介绍塑料土工格栅优点及加筋土原理和计算方法,采用分离式有限元法对未加筋、加一层筋材、加二层筋材等几种不同工况下的路堤进行计算分析,对计算所得的位移、应力结果进行分析,得到不同工况下的加筋效果,对工程设计有一定的参考价值。

By introducing of the advantage of plastic geogrid and the principle a nd calculation method of reinforced earth,calculation and analysis of embankment under several different running state was put forward using separated finite el ement,such as nonreinforcment,one-layer reinforcement,and two-layer reinforcemen t,and so on. At the same time,the displacement and stress result obtained from c alculation was analyzed so as to get reinforced effect in different running stat e.
