参建单位视角的装配式建筑施工安全风险因素

Safety Risk Factors of Prefabricated Building Construction from the Perspective of Participating Units

为预防装配式建筑工程项目出现施工安全事故,通过分析总结大量装配式建筑施工安全事故案例的基础上,从各参建单位的视角下,对装配式建筑施工过程中的安全风险因素进行提取,并结合具体项目和各因素的相互影响程度,运用决策试验和评价实验法(decision-making trial and evaluation laboratory,DEMATEL)建立矩阵模型计算,辨别出该项目安全风险因素的重要度排名,以及主要的原因因素和结果因素。研究结果表明:监理规划与实施细则的质量,装配式施工安全专项方案落实情况,危险性较大的分部分项工程论证等因素为装配式施工安全关键风险因素。最后提出对策建议,帮助管理人员做出相适应的预防措施。

In order to prevent construction safety accidents in prefabricated building projects,based on the analysis and summary of a large number of cases of prefabricated building construction safety accidents,the safety risk factors in the construction process of prefabricated buildings were extracted from the perspective of all participating units.Combined with the specific project and the degree of mutual influence of various factors,the matrix model was established by using decision-making trial and evaluation laboratory(DEMATEL)analysis method,and the importance ranking of the safety risk factors of the project,as well as the main cause factors and result factors were identified.The results show that the quality of supervision planning and implementation rules,the implementation of special safety plan for assembly construction,and the demonstration of most dangerous projects are the key risk factors for assembly construction safety.Finally,the countermeasures and suggestions were put forward to help managers make appropriate preventive measures.
