摘要
装配式建筑施工过程是实时的动态系统过程,因此建立施工安全动态评价尤为重要.首先从指标体系的动态性入手,基于数据挖掘技术,通过Apriori算法对现有评价指标进行关联分析;然后,结合施工过程寿命周期各阶段的特点,建立动态评价指标体系;最后利用变权和灰色聚类的方法对某装配式工程实例进行动态安全分析,得到各施工阶段及其下属指标的安全评价值,给出了安全管理建议,并验证了该动态评价体系的可行性.
Prefabricated building construction process is a real-time dynamic system process,so it is particularly important to establish a dynamic evaluation of construction safety.Firstly,this paper starts with the dynamics of the indicator system and based on data mining technology,carries on the correlation analysis of the existing evaluation indexes through Apriori algorithm;then,in combination with the characteristics of the construction process in different stages of the life cycle,the dynamic evaluation index system is established;finally,using the variable weight and grey clustering method,this paper conducts a dynamic security analysis of a prefabricated engineering example.The safety evaluation values for each construction stage and the subordinate indicators are obtained,safety management suggestions are offered,and the feasibility of the dynamic evaluation system is verified.
