结合京沪高速铁路某工区的实测观测资料,通过应用Asaoka算法和灰色系统GM(1,1)算法对实验数据进行研究,计算理论拟合高程并与实测高程进行比较,并通过相对应模型的高程残差的比较分析,表明所选灰色系统GM(1,1)算法拟合结果较好。 更多还原

【Abstract】 In this paper,combined with the measured observation data of a bid section of one work area of Beijing-Shanghai high speed railway,the author analyzed the experimental data of Asaoka algorithm and gray GM(1,1) algorithm,and calculated the theory fitted elevation and compared it with the measured elevation.By analyzing the elevation residual errors of corresponding model comparatively,the paper indicated that the fitting results of selected gray system GM(1,1) algorithm are better. 更多还原
