摘　　要：路基工程中不可避免遇到大量岩质边坡,岩质边坡稳定性评价是一项重要而复杂的工作,直接关系路基工程的设计、施工、工期造价等.基于四元联系数与熵权法的原理,建立一种岩质边坡稳定性评价方法.重点解决了评价因子筛选分级、权重确定、隶属度确定及综合评价公式等问题.利用该方法对某路基岩质边坡进行稳定性评价,稳定性等级为不稳定,结果准确,说明该方法具有一定可行性、实用性和科学性,可为类似工程提供经验和帮助.A large number of rock slope was inevitable in subgrade engineering, rock slope stability evaluation was an important and complicated work, which was directly related to the design, construction, duration and cost of subgrade engineering. Based on the principle of four element connection number and entropy weight method, a method of rock slope stability evaluation was established. The problems, such as evaluation factor screening, classification, weight determination, membership degree determination and comprehensive evaluation formula had been solved. The stability of a rock slope was evaluated by this method. The grade of slope stability is unstable and the result is accurate. The method is proved to be feasible, practical and scientific. It can provide experience and help for similar projects.
