摘　　要：基于循环荷载试验,对常规的指数曲线法、双曲线法、泊松曲线法等三种沉降预测模型进行了改进,增加了体现飞机循环荷载的对数分项,并用高斯-牛顿非线性回归法确定计算参数。通过浦东机场第一跑道沉降观测数据验证,改进后的预测模型具有更高的预测精度和适应性,可为跑道沉降预测提供借鉴。Based on cyclic loading experiment,commonly used settlement prediction methods-exponential curve method,hyperbolic method and poisson curve method are improved by adding an logarithm subentry to embody the affect of cyclic loading.The gauss-newton nonlinear regression method is used to determine the calculation parameters.t is verified by the settlement observation data of the first runway of Pudong airport that the improved prediction model has higher prediction accuracy and adaptability,and can provide reference for runway settlement prediction.
