摘　　要：针对特大型危岩体爆破削方治理过程中的风险因素具有随机性和不确定性,基于云模型理论,提出了组合赋权的危岩体云模型风险评价方法。从危岩体地质条件、环境因素、爆破削方施工及施工管理四个方面进行危险源辨识,建立特大型危岩体爆破削方治理风险控制安全评价指标体系,应用层次分析法对评价指标进行组合赋权处理。结合正向正态云模型和指标权重,计算评价对象的确定度及风险等级。应用该方法对甑子岩特大危岩体爆破削方治理过程进行了风险评价。该工程根据风险分析进行的危险源施工控制,能够满足施工安全。According to the randomness and uncertainty of the risk factors during the blasting cutting process for oversize dangerous rock mass,a risk assessment method by the cloud model theory and a combined weighting technology was proposed.The hazard identification considered four aspects:geological conditions,environmental factors,blasting cutting construction and construction management,and a safety evaluation index system was established accordingly.Furthermore,the combination and weighting of evaluation indexes were established by an analytic hierarchy process.Finally,the certainty degree and risk level of the evaluation object were calculated by combining with the positive normal cloud model and index weights.This method was applied to the risk assessment of the blasting cutting treatment process of Zengziyan oversize dangerous rock mass.According to the risk analysis,the risk source construction control of the project can meet the construction safety requirements.
