机场道面地基参数的识别与转换

提出一种机场道面地基参数识别与转换的方法，基于文克勒地基板理论和弹性半空间理论的计算模型，应用最小二乘法准则，通过实测挠度与理论挠度进行拟合来识别地基回弹模量E0和反应模量K，并依据实测点挠度相等的方法实现E0和K值之间的转换，实例计算表明所得结果具有较好的精度。

IDENTIFICATION AND TRANSFORMATION OF THE FOUNDATION PARAMETERS FOR AIRPORT PAVEMENT

In this paper, an identification and transformation method for foundation, parameters of airport pavement is proposed. Based on the theory of Winkler foundation plate and the theory of elastic semi-space model, the theoretical deflections of the airport pavement are derived. The least square method is used to identify the resilience modulus of foundation E0 and the response modulus K by fitting the testing and theoretical deflections. The transformations from E0 to K and from K to E0 are also realized by using the equal deflection values of testing points. A testing deflection of an airport pavement is used as a numerical example. Table 2 shows the identification results of K and E0. Table 3 and Fig.2 show the high accuracy of the results by comparing the testing deflection with the identification deflection. Table 4 and Table 5 show that we may easily transform E0 to K and then transform K to E0 of the airport pavement.
