Abstract:
对实际服役状态下的机场水泥混凝土道面板，布设传感器测试常见机型在飞机滑行状态下道面、基层顶面、地基的应力和应变，获得道面板结构各深度、位置以及基层、地基的动力响应曲线，各机型起落架作用下响应特征，分析飞机滑行状态与动力响应曲线的内在关系，推理道面板病害的产生原因，对工程设计提出了优化建议。
For the airport cement concrete pavement slab in actual service, sensors are arranged to test the stress and strain of the pavement, base top surface and foundation of common aircraft types under the taxiing state of aircraft, obtain the dynamic response curves of each depth and position of the pavement slab structure, base and foundation, and the response characteristics under the action of landing gears of various aircraft types, and analyze the internal relationship between the taxiing state of aircraft and the dynamic response curve. The causes of the diseases of the pavement slab are deduced, and the optimization suggestions for the engineering design are put forward.
