摘　　要：本文分析了不同边坡断面形式下岩体中应力状态的变化及其与边坡变形破坏的关系；建立了以岩体质量为基础的铁路岩石边坡坡度确定的定量分析方法；通过买例，对２５０ｍ高的河谷岸坡在铁路桥基荷载作用下的稳定性进行了分析，并确定出桥基的合理设置位置。In this paper, the stress feature and the interrelation between stress and failure inrailway rock slope, which is excavated in different section, are analysed with numericalmethod. Based on a field investigation into 183 railway rock slopes, a system in which slopeangle is calculated quantitatively and slope stability is evaluated according to rockmass quality is built. The engineering. practices shown that the system is successful and effective. Finally, an engineering practice of the analysis of slope stability and the location of bridgefoundation is provided as an example, in which the slope on river bank is 250m in height andbears 12000t load of bridge pier.
