摘　　要：深基坑支撑梁爆破拆除施工顺序的确定属于一个多因素决策分析问题,以AHP分析方法为基础对影响深基坑支撑梁爆破拆除施工顺序的因素进行分类和构建层次结构模型,并在分析过程中结合数值计算的方法改进了判断矩阵的确定方法,使得改进后的判断矩阵更具有客观性,提高了决策的可靠性。结合武汉某深基坑支撑梁爆破拆除项目,对其进行分区,通过Abaqus及AHP分析方法进行爆破拆除模拟计算,并在实际施工中验证了结论的正确性和可实施性。The determination of construction sequence of deep foundation pit support beam demolition belongs to a multi-factor decision analysis problem. The influence factors of blasting demolition of deep foundation pit support beam order were classified and the hierarchical structure model was established based on the AHP analysis method. The judging matrix was improved by numerical calculation during the process of analysis, which made the judgment matrix more objectivity and improved the reliability of decision-making. Combined with a blasting demolition of deep foundation pit support beam, by partitioning the foundation and taking the Abaqus and AHP analysis method for blasting demolition simulation, the effectiveness of the conclusion is correct and practical.
