摘要
为进行加筋土结构的变形分析 ,采用平面有限元法 ,考虑土和加筋土工布接触面的材料非线性 ,以及结构的施工过程 ,模拟土 -土工布的相互作用 ,在某加筋土土坝的分析中发现 ,坝体最大竖向沉降发生在断面高度的 2 / 3倍处 ,施工过程能降低土坝的竖向沉降 .分析结果为加筋土结构的设计提供依据
The plane finite element method was used to simulate the interaction of earth geotextile to analyze deformation of structure's the material nonlinear specialties of soil and contact are considered besides construction process. The analysis made on a certain reinforced dam discovers that maximum vertical settlement, which will be decreased with the effect of construction process, appears at 2/3 times of dam's height. The research results offer the reference for the design of reinforced earth structures.
