摘　　要：针对山区公路边坡点多、线长、规模小、地质资料少和现有岩体评价分级系统难以应用的特点,介绍了安全管理科学中的危险源理论,结合工程地质学和统计学方法,提出了公路岩质边坡危险源的概念和分类;结合岩土力学理论,采用人工智能方法,研究了山区公路岩质边坡危险源的辨识分级方法;借鉴社会经济学理论,提出了山区公路岩质边坡危险源的风险评估方法和相应的风险控制措施。通过多学科交叉的研究方法,形成了山区公路岩质边坡危险源的安全性评价理论体系。Considering the characteristics of multiple points, long line, small scale, lack geological data and difficult applying of present rock assessment system of the highway slope, the hazard theory of safety science is introduced. On the basis of this theory, the concept and categorization of the highway rock slope hazard are proposed by using engineering geology and statistical method, the identification and gradation methods of the highway rock slope hazard are studied by combining with the geomechanics and intelligent method, the risk assessment and risk control methods of the highway rock slope hazard are also proposed by referencing the social economics theory. Through the multi-disciplinary study, the theory system for the safety assessment of the hazard of the mountain highway rock slope is formed.
