摘要
通过对某土石坝测压管监测资料的分析,介绍了逐步回归方法应用于土石坝渗流监测资料分析的原理、步骤,以及变量的选取等问题。结果表明,逐步回归是渗流资料分析的一种有效方法,回归结果能基本反映土石坝渗流的主要影响因素,回归计算值与实测资料吻合较好。
By way of an example of analyzing piezometric monitoring data of an earth-rock dam, the application of stepwise regression method to safety monitoring data of earth-rock dams is presented, including the principles, procedures and selection of variables. The result indicates that stepwise regression is an efficient method. The regression solution can indicate the main factors that affect seepage through an earth-rock dam. The calculation result via the regression method is consistent with measured data.
