【摘要】：近年来,随着经济的发展,建筑规模逐渐扩大,许多的企业开始关注战略实施方法,对于项目群管理越来越重视。而建筑业作为高风险行业,由于建设规模大,整个建设过程中参与人员多,安全问题十分严峻,事故的发生对自然环境、社会经济和人民生活都会产生严重的影响。导致事故的根源为施工现场中潜在的危险源,但是,国内外目前对于项目群中危险源的研究较少。因此,本文以铜川市某小区建设为依托,对项目群危险源管理进行了研究。首先分析了项目群与单项目危险源管理的异同,建立了项目群危险源辨识的矩阵型组织结构及危险源辨识数据库。在项目寿命周期理论及PDCA循环理论的基础上,总结出了项目群危险源辨识的步骤,并绘制了从施工前、施工中、事故后及施工后危险源辨识的流程图。接下来从纵向及横向的角度对项目群建设过程中存在的危险源进行评价。在纵向评价中,结合了马尔科夫理论、模糊数学理论及可靠性理论,建立了基于可靠性分析的模糊马尔科夫模型。在横向评价中,构建了项目群中多个项目之间危险源的相关性评价指标体系,建立了基于信息熵与D-S证据理论的相关性评价模型。最后建立了项目群危险源控制组织结构,从不同的角度对危险源的控制方式进行了分类,总结了危险源的控制方法,对危险源按照危险程度进行了分级并阐述了危险源分级控制。研究结果表明:将本文的危险源管理体系应用到项目群建设过程当中,可以有效的解决项目群危险源管理中存在的问题,从而降低安全事故的发生,取得良好的经济和社会效益。文章研究成果可以为类似项目的危险源管理提供参考。
[Abstract]:In recent years, with the development of economy and the expansion of construction scale, many enterprises begin to pay attention to the method of strategic implementation, and pay more and more attention to project group management. The construction industry as a high-risk industry, because of the large scale of construction, the entire construction process involved in a large number of people, security problems are very serious, accidents on the natural environment, social economy and people's lives will have a serious impact. The root cause of the accident is the potential hazard source in the construction site. However, there is little research on the hazard source in the project group at home and abroad. Therefore, based on the construction of a small district in Tongchuan City, this paper studies the risk source management of project group. Firstly, the similarities and differences between project group and single project risk source management are analyzed, and the matrix organization structure and risk source identification database of project group risk source identification are established. On the basis of project life cycle theory and PDCA cycle theory, the steps of hazard source identification of project group are summarized, and the flow charts of hazard source identification before, during, after accident and after construction are drawn. Then the risk sources in the construction of the project group are evaluated from the vertical and horizontal angles. In longitudinal evaluation, a fuzzy Markov model based on reliability analysis is established by combining Markov theory, fuzzy mathematics theory and reliability theory. In the horizontal evaluation, the correlation evaluation index system of multiple projects in the project group is constructed, and the correlation evaluation model based on information entropy and D-S evidence theory is established. Finally, the organization structure of the project group risk source control is established, the control methods of the hazard source are classified from different angles, and the control methods of the hazard source are summarized. The hazard source is classified according to the degree of danger and the classification control of hazard source is expounded. The results show that the application of the risk source management system to the project group construction process can effectively solve the problems in the project group risk source management, thereby reducing the occurrence of safety accidents. To achieve good economic and social benefits. The research results can provide a reference for the risk management of similar projects.
