| 摘 要： | 岩盐公路破坏主要是由车辆载荷的振动引起的,公路运营期间所受到的荷载,不只是单一车辆荷载,常常是一列车队荷载,因此仅仅分析单一车辆对公路的作用显然不够全面.这里依据路面实际高程建立路基三维实体模型,基于Ansys程序的二次开发功能,对多车辆载荷作用下的岩盐公路的振动问题进行了分析.结果表明,振动加速度方面受车辆数目的影响较小,基本可以用单车辆的分析近似研究;应力方面,采用3车辆的分析基本可以近似研究多车辆对岩盐公路的作用.

| Abstract: | The rock salt highway's destruction is mainly caused by vibration of vehicles load.When put into operation,the highway does not endure one single vehicle load,but often a motorcade load.Therefore,obviously,it isn't complete only to analyze the effect of one single vehicle on highway.In the paper,3-dimentional entity model is built according to road surface actual elevation.And based on re-development function of software-ANSYS,vibrating characteristic of the rock salt highway under the multi-vehicle load is... |
