摘要
通过对公路高切坡安全影响因素的分析,取内摩擦角、粘聚力c及高切坡类型等作为评价指标,利用集对分析理论确立评价体系和评价模型。通过对重庆两巫路工程实例进行判别评价,验证结果与实际边坡安全等级相符,表明该理论方法具有可行性、有效性和科学性,可为其他相关领域提供一定的参考作用。
Being based on analysis of influencing factors for high-cut slope safety, the cohesion, angle of internal friction, high-cut slope type, topographic gradient and slope height have been chosen as evaluation indexes. 11- sing the theory of set pair analysis model, the evaluation system and evaluation model have been established. Then, by evaluating of the example of an expressway between Wushan and Wuxi in Chongqing City, the results have shown that the set pair analysis model could have the same results as with the actual safety level, which val-idates the rationality, effectiveness and scientific nature of the set pair analysis model, and could provide certain reference for other projects.
