| 摘 要： | 借助有限元软件ANSYS来分析地道桥结构与土的相互作用,采用三维实体建模方法模拟空间范围内的地道桥结构及其周围土体.分析有无列车荷载等两种不同工况下地道桥结构的位移、应力分布规律以及由其引起的地表沉降和土体的应力变化规律.通过有限元分析可以求出结构和土体的位移、应力峰值及其空间位置,为地道桥结构设计提供可靠的分析依据.

| Abstract: | The interaction between underpass bridge and soil is analyzed based on ANASYS FEM software. 3-D solid modeling is applied to simulating the underpass bridge saboteur and its surrounding soil in space. Comparing the analysis under the two different work conditions for there is train loading or not, the distributions of stress and displacement for the structure and soil are obtained. The positions of peak stress and peak displacement will be pointed out; and it is helpful to design underpass structure . |
