摘要
研究目的:山区高速公路建设不可避免地会遇到众多岩石边坡的稳定性问题,现行的岩石边坡稳定坡度设计时很少考虑岩体结构对边坡稳定性的影响。研究结论:对源范例边坡进行回判,回判率达85%以上。对常张高速公路12处结构型岩石边坡稳定性进行评判,结果与实际情况相符,说明本文提出的结构型岩石边坡稳定性评价模型是有效的。该方法可为道路边坡工程设计提供指导。
Research purposes： The stability of rock slope is an inevitable problem in construction of mountain expressway. The influence of rock mass structure on stability of rock slope is seldom taken into account in current design.
Research conclusions ~ The rock slopes in base case are re - evaluated and the accuracy ratio of back evaluation is above 85%. The stabilities of 12 structured rock slopes in Changde - Zhangjiajie expressway are evaluated by the model and the results are in good agreement with the actual conditions, which shows that the model of stability evaluation of structured rock slope based on case -based reasoning method in this paper is effective. The stability evaluating method for rock slopes can be a reference for design in rock engineering.
