摘　　要：针对海原大地震诱发的黄土滑坡滑距,通过单因素分析出对滑距的影响因素。再以多元回归分析为理论基础,对其中的30组数据进行分析,推导出滑距的预测公式。并将此公式用于其余调查的30组滑坡中进行验算,证明该公式较准确,可运用于对海原地震诱发的黄土滑坡的滑距推导。最后,提出对地震诱发的黄土滑坡滑距预测的应用前景设想。In relation to the sliding distance of the loess landslide induced by Haiyuan Earthquake, the factors affecting the distance was studied by univariate analysis. Furthermore, with the multiple regression analysis as the theoretical basis, the 30 groups of data therefrom were analyzed, thus to derive the formula predicting the sliding distance. Later, using this formula, the other 30 groups of data from this investigation were checked, through which the formula was proved to be correct and could be applied to calculate the sliding distance of the loess landslide induced by Haiyuan Earthquake. At last, the prospect imagine of application of sliding distance prediction in loess landslide induced by earthquake was constituted.
