摘　　要：为解决城市深基坑工程施工风险评价指标模糊性、随机性造成风险等级难以确定的困难,提出基于云模型的城市深基坑工程施工风险评价方法.从土方开挖、地基处理、基坑支护、排水降水和基坑监测五方面建立了城市深基坑工程施工风险评价指标体系;结合网络层次分析法(Analytic Network Process)和改进CRITIC法确定了各施工风险评价指标的权重;基于云模型理论构建了城市深基坑工程施工风险评价模型.最后对青岛蔚蓝生物深基坑工程应用所建模型进行案例分析,计算出总风险水平等级,并根据计算结果提出有针对性的措施,为青岛地区城市深基坑工程施工开挖的风险评价提供参考.The construction risk level of urban deep foundation pit engineering is difficult to determine due to the fuzzy evaluation index and randomness. As a result, a construction risk evaluation method for urban deep foundation pit engineering based on cloud model operator is proposed. Firstly, construct an urban deep foundation pit engineering construction risk evaluation index system from five aspects, earthwork excavation, foundation treatment, foundation pit support, drainage of precipitation and foundation pit monitoring. Secondly, Considering the subjective weight and objective weight, combined with Analytic Network Process and improved CRITIC method, the weight ofrisk index was determined. Then construct the construction risk evaluation model of urban deep foundation pit engineering based on cloud model method. Finally, applied that model to evaluate the construction risk of the Vland Biotech deep foundation pit project in Qingdao. And the total risk level is calculated, and targeted measures are proposed based on the calculation results to provide reference for the risk assessment of the construction excavation of the urban deep foundation pit engineering in Qingdao.
