为保障装配式建筑施工过程的安全,降低安全事故发生率,解决装配式建筑施工安全风险评估问题,根据常见的施工安全问题,并针对装配式建筑施工过程的特点,结合实地调研及文献查阅,构建了基于熵权-未确知测度理论的装配式建筑施工安全风险评估模型,并将该模型应用于工程项目中,取得了良好的效果.研究结果表明,该模型计算过程简单,结果合理可靠,为有效进行装配式建筑施工安全风险评估提供了新的思路.

In order to ensure the safety of fabricated building construction process, reduce the incidence of safety accidents and solve the problem of fabricated building construction safety risk assessment. According to the common construction safety problems, and the characteristics of fabricated building construction process, combined with field investigation and literature review, a safety risk assessment model of prefabricated building construction based on the entropy weight-uncertainty measurement theory was established, then the model was applied in engineering project, and the good result was obtained. It showed that the calculation process of is clear and the results are reasonable and credible, and it provides a new idea for the effective assessment of safety risk in the construction process of fabricated building.
