多个项目并行施工的安全事故因素相关性研究

Research on correlation among safety factors in parallel construction of multi-project

针对目前缺少对多个项目并行施工的安全事故因素相关性研究,以致于当施工项目发生重大安全事故后就对大范围内项目停工整改的问题,提出了多个项目并行施工的安全事故因素相关性指标体系,建立基于信息熵与D-S证据理论的相关性评价模型。以铜川市某小区建设项目为背景,对小区建设过程中多个项目并行施工的安全事故相关性进行分析。在采用德尔菲法跟模糊分析法基础上,使用信息熵确定指标的权重,并引入D-S证据算法,从而得出多个项目并行施工的安全事故相关性等级。计算结果表明,模型可以准确地计算出多个项目并行施工的安全事故相关性等级,能更好地满足多项目管理的需求,从而降低不必要的人力、财力的浪费。

There was a lack of research on the correlation of safety factors in parallel construction of multi-project. When a serious accident happened to a construction project,a wide range of the project would be stopped to readjust. Therefore,a correlation index of safety factors in parallel construction of multi-project was put forward. A correlation evaluation model was established based on Information Entropy Theory and D-S evidence theory. Based on the parallel construction of a residence in Tongchuan,the correlation of safety factors in the construction was analyzed. On the basis of Delphi Method and Fuzzy Analysis Theory,the weight of each index was determined by the Information Entropy Theory. Moreover,the D-S evidence theory was introduced to obtain the correlation level of the safety factors in the parallel construction. Analysis results show that the correlation level of the safety factors obtained from the model is accurate and can better meet the needs of multi project management,which reduces the unnecessary waste of human resources and funds.
