装配式建筑施工安全风险因素研究

Research on Safety Risk Factors in Prefabricated Building Construction

摘要: 为实现对建筑施工安全风险的有效把控，本文识别了来自人、物、技术、管理和环境5个方面的15个关键施工安全风险影响因素。利用DEMATEL-ISM建模方法，首先得到各因素的中心度和原因度，其次构建多层递阶结构模型，最后分析得出建筑施工安全风险的根本影响因素。研究表明：装配式建筑施工过程中安全风险的影响因素可划分成3阶6层递阶结构，包括4个直接影响因素，8个中间影响因素和3个根本影响因素。

Abstract: In order to effectively control the construction safety risk, this paper identifies 15 key construction safety risk influencing factors from five aspects: people, things, technology, management and environment. Using the DEMATEL-ISM modeling method, the centrality and cause degree of each factor are obtained firstly, then the multi-layer step-by-step structure model is constructed, and finally the fundamental influencing factors of construction safety risk are analyzed. The results show that the influencing factors of safety risk in the construction process of prefabricated buildings can be divided into 3-stage and 6-layer progressive structures, including 4 direct influencing factors, 8 intermediate influencing factors and 3 fundamental influencing factors.
