【摘要】：20世纪90年代以来，随着国民经济和交通事业发展的需要，我国高速公路和铁路的建设得到了全所未有的发展，大跨度桥梁建设进入了一个崭新的发展时期。作为交通线上至关重要的一环，越来越多的大型、特大型桥梁相继建成。桥梁工程的基本特点是投资大、技术复杂、工程点多线长面广、工程寿命周期长，一旦发生事故后果严重，所以桥梁工程与其他产业相比，具有更大的风险。但是，桥梁工程的风险管理在我国还是一个比较薄弱的环节。因此从理论和实践的两个方面，对桥梁工程风险管理进行研究，对项目风险进行分类识别，提出防范控制的方法，对于有效减少风险事件的发生有着十分重要的积极意义。潍坊白浪河大桥项目如能顺利实现，将对潍坊的经济和生态环境有重大的影响。所以本文以潍坊白浪河大桥为背景，通过研究国内外一些理论和方法，构建了工程项目风险的分析和评价指标体系，使得风险分析和评价的结论更为科学。本文主要分析了潍坊白浪河大桥的项目整体情况，认为在大桥设计、建设施工、运营管理各个不同阶段中，都存在着众多的风险，尤其以建设期的风险最为集中，各种不利因素会在这个时期集中反应出来。讨论和识别了潍坊白浪河大桥的风险构成，在项目风险识别中，使用头脑风暴法，可知潍坊白浪河大桥至少面临29个风险因素，如成本超支、工期延误、资金不足等。并通过建立项目风险评价指标体系，确定白浪河大桥主要面临8种风险，之后对潍坊白浪河大桥的风险提出潍坊白浪河大桥风险应对方案，针对不同等级的风险采取不同的应对方式，构建了潍坊白浪河大桥风险防范体系，防范风险管理的进程，以便有效地实施风险管理，降低风险，最大限度地避免或减少风险事件的出现，使潍坊白浪河大桥能够在最低风险范围之内，将项目的风险降至最低。
[Abstract]:Since the 1990s, with the need of the development of national economy and transportation, the construction of highway and railway in our country has been developed in a way that has never been done before. The construction of long-span bridges has entered a new period of development. As a crucial link in the traffic line, more and more large and super-large bridges have been built one after another. The basic characteristics of bridge engineering are large investment and complex technology. Because of the wide range of engineering sites, long project life cycle and serious accident consequences, bridge engineering has a greater risk than other industries. However, The risk management of bridge engineering is still a weak link in our country. Therefore, this paper studies the risk management of bridge engineering from the two aspects of theory and practice, classifies the risk of the project, and puts forward the methods of prevention and control. It is very important to reduce the occurrence of risk events. If the project of Weifang Bailang River Bridge is successfully realized, it will have a great impact on the economic and ecological environment of Weifang. Therefore, this paper takes the Bailang River Bridge in Weifang as the background, and studies some theories and methods at home and abroad. The analysis and evaluation index system of engineering project risk is constructed, which makes the conclusion of risk analysis and evaluation more scientific. This paper mainly analyzes the overall situation of the project of Weifang Bailanghe Bridge, and thinks that there are many risks in the different stages of design, construction and operation management of the bridge, especially in the period of construction. All kinds of adverse factors will be reflected in this period. The risk composition of the Bailang River Bridge in Weifang has been discussed and identified. In the project risk identification, using the brainstorming method, it can be known that the Bailang River Bridge in Weifang faces at least 29 risk factors. For example, cost overruns, construction delays, insufficient funds, etc. Through the establishment of the project risk evaluation index system, it is determined that the Bailang River Bridge mainly faces 8 kinds of risks. Then put forward the Weifang Bailang River Bridge risk response plan, aiming at different levels of risk to take different coping methods, build Weifang Bailang River Bridge risk prevention system, prevention risk management process, In order to effectively implement risk management, reduce risk, avoid or reduce the occurrence of risk events to the maximum extent, so that Weifang Bailang River Bridge can reduce the project risk to the lowest within the minimum risk range.
