为加强水利水电工程施工的安全管理, 预防和控制事故的发生, 通过建立结构方程进行施工安全风险的分析, 设定4个潜变量及12个观测变量, 应用AMOS 17.0 进行方程计算, 得到12个路径系数和6个相关系数。其中企业影响与组织机构, 施工现场与技术措施, 人员素质与教育培训, 安全管理与安全监督之间路径系数较大, 分别为3.03, 1.36, 1.36, 1.00, 说明该4组因素有较强联系。采取的措施为增强企业影响力、完善企业的组织结构、建立完善的监督机制, 并对施工人员进行严格的安全培训等措施完善施工安全工作。为建立合理的安全评价指标系统提供了参考借鉴。
Abstract
To strengthen the safety management for hydroproject construction and to prevent and control accidents, the construction safety risk was analyzed by using structural equation modeling. A theoretical model which contains 4 latent variables and 12 observed variables concerning the construction safety was established based on structural equation. The coefficients were calculated by using AMOS 17.0. Twelve path coefficients and six correlation coefficients were obtained. The path coefficients respectively between company influence and company organization, construction site and technical measures, personnel quality and personnel training, as well as safety management and safety supervision were 3.03, 1.36, 1.36, 1.00, indicating strong connection between the factors. Measures inclusive of improving company influence, company organization, supervision mechanism, strict safety training and education were proposed. This research could be a reference for the reasonable safety assessment system in engineering construction.
