摘要/Abstract

摘要： 为预防施工安全事故,梳理文献和安全技术规程,从预制构件生产、进场及运输、存放、吊运、安装5个阶段,识别装配式建筑施工安全25个主要风险,并通过调查问卷收集数据;采用结构方程模型(SEM)进行25个风险的验证性因素分析(CFA),筛选出18个关键风险因素,并分析5个阶段风险因素间的关联性。结果表明:装配式建筑施工过程各阶段的风险排序为:预制构件存放阶段＞吊运阶段＞进场及运输阶段＞安装阶段＞生产阶段;各阶段存在安全风险的关联性排序为:存放-吊运阶段＞生产-进场及运输阶段＞存放-安装阶段＞存放-进场及运输阶段＞吊运-安装阶段＞生产-吊运阶段＞安装-进场及运输阶段＞吊运-进场及运输阶段＞生产-存放阶段＞生产-安装阶段。

Abstract: In order to prevent construction accidents, relevant literature and safety technical regulations were reviewed and 25 major risks in prefabricated building construction were identified from five stages of production, approach and transportation, storage, hoisting and installation of prefabricated components. Data were collected through questionnaires and the SEM was used to conduct CFA of these 25 risks and then 18 key risk factors were screened. The correlations among risk factors in five stages were analyzed. The results show that the sequence from high to low of risks in each stage of prefabricated building construction process is: prefabricated components storage stage, hoisting stage, approach and transportation stage, installation stage, and production stage, and that the sequence from high to low of correlations of each stage is: storage-hoisting, production-approach and transportation, storage-installation, storage-approach and transportation, hoisting-installation, production-hoisting, installation-approach and transportation, hoisting-approach and transportation, production-storage, and production- installation.

Key words: prefabricated building, construction, safety risk, structural equation model(SEM), confirmatory factor analysis(CFA)
