摘　　要：本文在12条山区铁路147个边坡工点调查基础上,分析了影响边坡稳定性的因素。统计分析表明,由回弹值(R),岩块咬合系数(E),视块度(D)以及地下水影响系数(W)所建立的边坡岩体质量 BYZ(BYZ=R·E·D·W)与边坡高度,坡角有明显的相关性。根据 BYZ 将边坡岩体分为六类,分别给出坡高和坡角的建议值。Based on the investigation of 147 slopes along 12 railway linesin mountainous region,the factors of influence on slope stabilityare analysed.The results show that there is a good relationbetween slope rockmass quality(BYZ),which depends onrebound value(R),grip coefficient(E),apparent block size(D)and ground water(W),and slope height and angle.For BYZ,the slope rockmass is divided into six types,with suggestedheight and angle for each type.
