| 摘 要： | 以ansys为计算平台,建立了列车—轨道—基础—结构的三维动力相互作用分析模型,分析了列车运行引起的环境振动问题及对周围结构的影响,结果表明:在软土情况下,列车引起的建筑物的竖向振动比较大；建筑物的振动也基本随车速的增大而在增大；轴重大的货车引起的振动响应比客车要大；改变建筑物的自身结构刚度特性对水平向加速度的改变较明...

| Abstract: | Based on analysis for computing platforms,this paper establishes a 3-d dynamic interaction analysis model of the train-rail-foundation-structure,and analyzes the vibration in train operation and its influence on surrounding structures.The results show that in the soft soil circumstance,vertical vibration of the building is great,that vibration of the building increases with the increasing speed of the train,that vibration of large vehi-cles is larger than passenger cars.Changes of the building structure sti... |
