| 摘 要： | 本文利用全国铁路147个岩石边坡的调查资料，按边坡稳定状况分成三
类和二类:即稳定、基本稳定和不稳定，以及稳定和不稳定。选择岩石
回弹值R、岩体完整性系数I。等n个参数和岩坡综合相时贯通度GP、
岩坡综合稳定性系数GX等5个参数为判别变量。采用逐步判别分析方
法时铁路岩石边坡的稳定性进行评价，其结果比较理想。

| Abstract: | The method of progressive discrimination analysis is used toevaluate the stability of railway rock slopes.Based on 147field materials,railway rock slopes are classified into threetypes:stable,substable,and unstable;and into two types:stable and unstable,with eleven parameters and five parametersas two sets of discrimination variables,including rock reboundnumber R,rockmass intact coefficient I_c,mean apparent-persistence GP,mean stability coefficient GK,etc.Calculatedresults show the feasibility of the method. |

| Keywords: | railway rock slope slope stability progressive discrimination discrimination variable |
