基于有限元法的悬臂式挡土墙墙顶变形影响因素分析

悬臂式挡土墙墙顶位移的影响因素是多方面的,从安全角度出发,基于有限元法对悬臂式挡土墙墙顶的变形影响因素进行了分析,并定量分析了各影响因素,如交通荷载与填土力学性质对墙顶位移的敏感性与挡土结构稳定性变化规律。实际工程算例表明,此方法能够确保悬臂式挡土墙的安全,且具有一定的适用性。

On Affecting Top Deformation of Cantilever Retaining Wall Based on Finite Element Method

The factors affecting the displacement on top of cantilever retaining wall are diverse. From the perspective of safety, these factors were analyzed by means of finite element, and then the change law of each factor, such as the sensitivity of traffic load and filled earth’s mechanical properties to the top displacement, and the stability of retaining structure, was studied by quantitative method. The calculation example of project case shows that this method may ensure the safety of cantilever retaining wall and has certain applicability.
