论文根据填埋体沉降监测数据样本量较少的特点,运用规则张力样条插值算法,以钻孔第一层数据为实验对象,对小样本数据进行插值。试验过程中,从理论和实验两个角度分析各参数对插值结果的影响规律;以残差均方差、交叉验证均方差等作为评定指标,找出能够得到最优预测表面的最佳参数值。实验结果表明,选择最优参数值的规则张力样条插值工具所得出的插值结果并不理想,各项指标均不能达到常规要求之内。对结果进行分析表明,该结果可能是未考虑原始数据的规律引起的。
In this paper, based on characteristics of small sample monitoring landfill settlement data, interpolated the first layer data of the drill with Regularized Splines with Tension model. During the experiment, both from the theoretical and experimental point of view of the results of various parameters on Interpolated of law. Choose the residual mean square and prediction mean square prediction as a measure of index to found the optimal parameter values. Experimental results show that the Interpolated results are not satisfactory, all targets were not reached within the normal requirements. The results were analyzed, the analysis showed that the results may be due to not take into account the law of original data caused.
