机轮荷载差异对机场水泥混凝土双层板的影响研究

摘要

通过试验研究了四种不同机型的机轮荷载对直接式双层水泥混凝土道面板的影响，并用ANSYS软件进行了数值模拟。研究发现，双层板的最大拉应力出现在板纵缝边缘中部，最大拉应力和道面弯沉均随着机轮荷载的增大而增大，且模拟的结果与试验结果基本一致，验证了通过ANSYS软件进行机场道面双层板受力分析的可行性。%Some experiments were conducted to research the impact of wheel loads of four different kinds of planes on direct dou-ble-layer plate in airport cement concrete pavement,and ANSYS software was used to conduct numerical simulation.The result shows that maximum tension stress appears at the middle of the plate edge of longitudinal seam,and maximum tension stress and pavement deflection increase with the increase of wheel load.Simulation results and experimental results are nearly the same,which proves the feasibility of the way to analyze the pressure of double-layer plate in airport cement concrete pavement by ANSYS software.
