摘　　要：为了保证地铁盾构施工风险评价的客观性,构建了基于组合赋权云模型的地铁盾构施工风险评价模型。首先,通过文献调研和咨询专家从“人、机械、技术和环境”四个角度建立符合条件的地铁盾构施工风险评价指标体系;其次,考虑单一指标赋权的局限性和片面性,采用G1法和COWA算子博弈组合对评价指标进行赋权,同时,为解决评价施工风险存在的模糊性和随机性,采用云模型对地铁盾构施工风险具体评估;最后,以青岛地铁1号线“安安”区段为例,通过MATLAB绘制该项目的整体施工风险综合评价云图并确定施工风险等级为“较低风险”,与项目实际监测结果一致,以此验证该评价模型的科学性和合理性。In order to ensure the objectivity of the risk evaluation of subway shield construction,this paper builds a model of the risk evaluation of subway shield construction based on the combinational weighting cloud model.Firstly,through literature research and consulting experts,a qualified risk evaluation index system for subway shield construction is established from the perspectives of man,machine,technology and environment.Secondly,considering the limitation and one-sidedness of single index weighting,the evaluation index is weighted by combining the G1 method(order relation analysis method)and the COWA operator game.At the same time,in order to solve the fuzziness and randomness in the evaluation of construction risk,the evaluation cloud map is drawn by the cloud model to evaluate the subway shield construction risk.Finally,taking the An’an Section of Qingdao Metro Line 1 as an example,this study draws the comprehensive evaluation cloud map of the overall construction risk of the project by using MATLAB,and the construction risk level is hereby confirmed to be low,which is consistent with the actual monitoring results of the project,thus verifying the scientific nature and rationality of the evaluation model for the project construction risk evaluation.
