摘要
装配式建筑项目在施工过程中面临高度的复杂性和风险性,对其进行安全风险评估具有重要的实践意义。以装配式建筑施工项目为研究对象,提出了一种基于改进物元可拓法的装配式建筑施工安全风险评估模型。首先,构建了一套装配式施工安全风险评价指标体系,并通过结构熵权法对各评价指标进行权重分配,以确保评估过程的客观性和科学性。然后,采用贴近度原则代替最大隶属度原则,改进了传统物元可拓模型。以青岛市某装配式建筑项目为例进行验证,结果显示,改进后的模型可以有效解决施工安全风险评估中对模糊性和随机性考虑不足的问题,能够直观地反映项目的风险倾向和趋势,可为装配式建筑施工安全风险的预警和防控提供科学依据。
The construction of prefabricated buildings projects faces high complexity and risks during the construction process,making safety risk assessment of great practical significance.Taking prefabricated building construction projects as the research object,a prefabricated building construction safety risk assessment model based on improved matter-element extension method is proposed.Firstly,a set of evaluation index system for safety risk assessment in prefabricated construction is constructed,and the weights of each evaluation index are allocated through structural entropy weight method to ensure the objectivity and scientificity of the assessment process.Then the traditional matter-element extension model is improved by replacing the maximum membership degree principle with the proximity principle.Finally,the model is validated using a prefabricated building project in Qingdao City as an example.The validation results show that the improved model can effectively address the lack of consideration for fuzziness and randomness in construction safety risk assessment,intuitively reflect the project′s risk tendency and trend,and provide a scientific basis for early warning and control of safety risks in prefabricated building construction.
