摘要
基于Winkler弹性地基板理论,提出机场道面在静力荷载作用下的挠度计算和运动荷载作用下的响应分析,并将各自计算的理论挠度曲线与实测的挠度曲线应用最小二乘准则进行曲线拟合,从而识别出机场道面的地基反应模量K,继而进一步分析机场道面的承载力。通过某一机场的实测数据进行计算,表明本文所得结果具有较好的精度。
Based on the theory of Winkler foundation plate, the deflection calculation u nder static loads and response analysis under moving loads for airport pavem ent are proposed respectively. The least square method is employed to identify t he response modulus of the foundation for airport pavement, by fitting the meas ured and theoretical calculated deflection curves. The load beari ng capacity of the pavement is also analyzed.A numerical example shows the identification resul ts and the accuracy of the approach.
