摘　　要：为弥补现有高边坡安全风险评估方法的不足,提高评估精度,借鉴可拓学原理,从风险事故发生的可能性和严重程度两个维度对高边坡施工安全风险进行动态评估。在量化风险评估等级标准的基础上,建立高边坡施工安全风险评估的可拓物元模型,通过关联函数计算各层评价指标与评估等级的关联度,根据各指标的权重计算综合关联度,以确定风险事故发生的可能性和严重程度等级及安全风险等级。最后,将评估方法用于实例中,分析结果可为采取相应的控制措施提供决策支持。To improve the evaluation precision of road high-slope, the principle of extenics was em- ployed to evaluate the security risk of high slope construction from the two dimensions of accidents risk likelyhood and severity degree of the accident. Based on the quantitative evaluation grade of risk assessment, an extension matter-element model of high slope construction security risks was estab- lished. The correlation degree of each layer of evaluation index and evaluation grade was calculated in accordance with the weight of individual index to determine the accidents risk likelyhood, the se- verity degree and the security ute to the decision-making for risk grade. The results indicate that the evaluation model can contrib- taking appropriate control measures.
