基于ANP-灰色聚类法的地铁深基坑施工安全风险评估

Construction of metro pit security risk assessment based on the method of ANP and Grey Clustering

结合青岛地铁1号线贵州路站深基坑工程实例,根据地铁深基坑施工特点,识别出该深基坑工程施工过程中安全风险因素及指标.利用ANP建立风险评价模型并计算出相应指标的权重,运用灰色聚类法进行安全风险评价,确定安全等级,建立基于ANP和灰色聚类法的地铁深基坑施工安全风险评估模型.计算结果证明该评价模型是可行的,对于青岛地铁施工安全具有积极的借鉴意义.

Taking the deep foundation pit project of Guizhou Road subway station of the Met-ro Line 1 of Qingdao as an example, this paper identifies the safety risk factors and indicators existed in deep excavation process according to the characteristics of the construction of sub-way pit. The paper establishes risk assessment models using the method of ANP , and calcu-lates the corresponding index weights using grey clustering method to assess safety risk and determine the level of security. Finally？ the metro pit construction safety risk assessment model based on ANP and grey clustering method is established. Calculation results show that the evaluation model is feasible and has a positive significance for Qingdao subway con-struction safety.
