摘要
介绍塑料土工格栅的特点以及塑料土工格栅加筋土挡土墙的结构组成,从此种结构的力学特性出发,建立有限元计算模型,将整个结构划分为土体单元、筋材单元和接触单元,用分离式有限元法对加筋土挡土墙进行计算分析。结果表明,此方法是合理的。
The feature of the polymer geogrids and the composition of the polymer geogrid reinforced earth retaining wall are introduced. To simulate the structural mechanical characteristic of the reinforced earth retaining wall, a finite element model is developed. The model is made of soil element, reinforcement element and contact element. The reinforced earth retaining wall is calculated with the finite element model. The results manifest the finite element method is reasonable for the reinforced earth retaining wall.
