基于组合赋权二维云模型的装配式建筑构件吊装施工安全风险评价
Safety risk assessment of assembly building component hoisting based on combined weighted two-dimensional cloud model
【摘要】 为了确保装配式建筑吊装施工过程的安全性,本文将采用组合赋权二维云模型评价方法对兰州市某装配式工程的吊装施工过程存在的安全问题进行风险评估。从人、物、技术方案、环境和现场管理5个方面展开系统研究,围绕施工人员技术能力、构件质量缺陷等17项Ⅱ级风险评估指标确立了整个项目的风险评价体系。以改进G2法与反熵权法对主客观权重进行线性最优组合确定其权重,在输出的二维云图后应用相近度公式验证确切的构件吊装施工过程的风险等级为Ⅲ级,此风险等级可接受,符合该工程实际风险管理情况,研究结果表明:该模型建立的风险评价方法合理,可应用于实际工程。
【Abstract】 In order to ensure the safety of assembly building hoisting construction process,this paper will use the combined weighting two-dimensional cloud model evaluation method to evaluate the safety problems existing in the hoisting construction process of a prefabricated project in Lanzhou City. The risk evaluation system of the whole project is established from 5 aspects of human,material,technical scheme,environment and site management,and 17 grade II risk assessment indexes,such as technical ability of construction personnel and quality defects of components,are established. Based on the improved G2 method and the inverse entropy weight method,the linear optimal combination of subjective and objective weights is used to determine the weight. The risk grade is acceptable and accords with the actual risk management of the project. The results show that the risk evaluation method established by the model is reasonable and can be applied to practical engineering.
