有限元分析填土的物理性质对加筋土挡土墙边坡变形的影响

Use Finite Element to Analyze the Effect of Banket's Physical Property on Deformation of Reinforced Earth Wall

根据填土的不同物理性质,计算出了最大位移与最大沉降,结果表明:填土的弹性模量、粘聚力、内摩擦角都对加筋土挡土墙边坡的最大位移与最大沉降有着不同的影响,其中弹性模量对边坡的最大位移与最大沉降影响最为显著。因此,采取合理的填土是控制加筋土挡土墙边坡位移,是达到最优设计目标的重要手段。

According to different physical property of banket, we can calculate maximum displacement and maximum sedimentation. The result shows that banket's modulus of elasticity, adhesion and internal friction angle affect on the maximum displacement and maximum sedimentation of side slope of reinforced earth wall. Among them, modulus of elasticity affect the most on the maximum displacement and maximum sedimentation of side slope. Hence, reasonable banket can prevent side slope's displacement.
