| 摘 要： | 基于Winkler弹性地基板理论,建立机场道面在运动荷载作用下的数学模型并进行动力响应分析,将计算所得的理论挠度曲线与实测所得的实验挠度曲线应用最小二乘法进行曲线拟合,从而识别出机场道面地基反应模量.通过对某一机场分别用飞机及重型车加载的实测数据进行计算,表明所得结果具有较好的精度.

| Abstract: | Based on the theory of Winkler foundation plate, the mathematical model and the dynamic response analysis under dynamic loads for airport pavement are proposed in this paper. The least square method is used to identify the foundational response modulus of airport pavement by fitting the testing deflection and the theoretical deflection.With the moving loads of an airport and a heavy vehicle, an numerical example shows the identification results and the high accuracy of the approach. |
