【摘要】：目前随着我国经济不断发展,地铁项目的建设取得了辉煌成绩。但与此同时,在地铁项目的建设过程中也会出现众多问题,诸如施工安全事故频发、投资严重超支、工期延后等。在城市地铁建设过程面临的众多问题中,安全问题当属重中之重。地铁项目施工过程中导致的人员伤亡以及对周围濒临建筑物的影响,已经受到了社会的广泛关注。目前,我国正处于城市轨道交通项目的建设高潮,但工程项目管理经验相对不足,工程风险和安全隐患不同程度的存在。由于地铁施工独有的特性,因此影响施工安全的风险因素之间并不是孤立存在的,而是相互联系,相互作用。如何将风险因素进行辨别,如何建立针对地铁施工工程特点的风险评估模型,是当前地铁工程界研究人员所迫切需要解决的问题之一。本文以深圳地铁七号线工程实例为依托,在总结前人研究成果的基础上,结合风险管理理论知识以及深圳地铁七号线的实际情况,对深圳地铁七号线工程项目施工过程进行风险辨别、风险估计和风险评价,利用风险识别三因素法就施工过程中工程项目的地质风险、施工风险以及环境风险因素进行识别,再结合专家调查法和模糊综合评价法对上述各风险因素进行评价,将定性的问题转变成定量评价,并提出相应的措施,减少风险所带来的危害,对其它同类型项目起到借鉴意义。
[Abstract]:At present, with the continuous development of our economy, the construction of subway projects has made brilliant achievements. But at the same time, many problems will appear in the construction process of subway project, such as frequent accidents of construction safety, serious overspending of investment, delay of construction period and so on. In the process of urban subway construction many problems, safety issues should be the most important. The casualties caused by the construction of subway project and its influence on the surrounding buildings have been paid more and more attention by the society. At present, our country is in the urban rail transit project construction climax, but the engineering project management experience is relatively insufficient, the engineering risk and the safety hidden danger existence in varying degrees. Because of the unique characteristics of subway construction, the risk factors that affect the construction safety are not isolated, but are related and interact with each other. How to distinguish the risk factors and how to establish the risk assessment model according to the characteristics of subway construction engineering is one of the urgent problems that need to be solved by researchers in the field of subway engineering at present. Based on the example of Shenzhen Metro Line 7, based on the previous research results, this paper combines the theoretical knowledge of risk management and the actual situation of Shenzhen Metro Line 7. Risk identification, risk estimation and risk evaluation are carried out in the construction process of Shenzhen Metro Line 7 project. The geological risk, construction risk and environmental risk factors of the construction process are identified by using the risk identification method. Combining the expert investigation method and fuzzy comprehensive evaluation method to evaluate the above risk factors, the qualitative problem is transformed into the quantitative evaluation, and the corresponding measures are put forward to reduce the harm caused by the risk.
