以用于磁悬浮列车轨道梁的先张法预应力台座为工程背景 ,着重分析上海磁悬浮列车工程的台座设计方案及实际设计中遇到的问题。用三维有限元计算分析了台座及其桩的受力和变形特性 ,并且通过使用阶段的实际观测验证了计算分析结果 ,满足了实际工程的需要
Taking the pretensioned prestressed pedestal used for the track beam of the maglev train as the engineering background, the pedestal design scheme and the problems encountered in the actual design of the maglev train project in Shanghai are emphatically analyzed. The three-dimensional finite element method was used to analyze the stress and deformation characteristics of the pedestal and its pile, and the results of the calculation and analysis were verified through the actual observation of the use stage, which met the needs of the actual project
