【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_c 等11个参数和岩坡综合相对贯通度 GP、岩坡综合稳定性系数 GK 等5个参数为判别变量。采用逐步判别分析方法对铁路岩石边坡的稳定性进行评价,其结果比较理想。更多还原

【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.更多还原
