| CA砂浆弹模对框架板式轨道翘曲应力的影响分析(51 卷) |
| 英文标题 |
| Analysis about influence of cement emulsified asphalt mortar’s modulus of elasticity on framed slab track warping stress |
| 摘要 |
| 采用有限元分析法，对框架板在温度梯度作用下的翘曲应力进行仿真计算，分析了砂浆弹性模量的变化对框架板温度效应的影响。结果表明：在温度荷载作用下，框架板式轨道框架角点处和凸台边缘处将产生局部翘曲应力的集中，最大的翘曲应力产生在轨道板角点处，并产生最大的翘曲位 |
