摘要
分析了框架板式无碴轨道结构力学模型,对框架板式无碴轨道扣件刚度和乳化沥青水泥砂浆层弹性模量两种参数组合变化进行了计算,得出了框架板和乳化沥青水泥砂浆层内的主拉应力、主压应力、剪应力和弯矩最大值的变化趋势。
It analyzes the structure mechanic model of frame board undreg orbit, calculates the change of two parameters combination, buckles rigidity of frame board undreg orbit and resilience module of emulsification bitumen cement sand-starch layer, reaches the change tendency of host pulling stress, main pressuring stress, cut-stress and maximum of bending moment in the frame board and emulsification bitumen cement sand-starch layer.
