【摘要】：随着城市化进程的加快,公路运营车辆逐渐增多,平交路口已不能满足出行需求。在此环境下各大城市均加快高架工程建设,如此快速、大量地进行高架工程建设必然存在极大风险,在可能发生的风险中,桥梁工程建设过程中施工风险发生的可能性最大。本文首先分析了桥梁工程风险评估的国内外现状,介绍了风险评估各环节的实施过程,然后以A高速公路高架工程为实例,对其施工风险进行评估。在建立风险识别模型基础上,主要运用德尔菲法识别A高速公路高架工程的施工风险因素,通过风险识别确定本工程最终风险清单;建立了风险评价模型,运用模糊层次法确定A高速公路高架工程施工风险各因素权重,并运用模糊综合法对本工程施工风险进行了定量评价,得出本工程风险等级为“高”,即本工程存在高风险,定量评价结果为本工程风险应对策略的指导提供了有力的依据。在风险评价结果的基础上,本文给出A高速公路高架工程的风险应对对策,并制定了详细的应对措施,从而有效地提高了本工程的风险管理水平。本文的研究不但可以指导本工程风险管控,亦可作为类似高架工程风险评估的参考。
[Abstract]:With the acceleration of the urbanization process, the number of vehicles running on the road is gradually increasing, and the level intersection can no longer meet the travel demand. In this environment, all the major cities are speeding up the construction of elevated engineering, so fast. A large number of elevated engineering construction is bound to have great risks, in the possible risks. In the process of bridge construction, construction risk is the most likely. Firstly, this paper analyzes the current situation of bridge engineering risk assessment at home and abroad, and introduces the implementation process of each link of risk assessment. Then take A Expressway viaduct project as an example to evaluate its construction risk. On the basis of establishing risk identification model, the paper mainly uses Delphi method to identify the construction risk factors of A Expressway elevated Project. Determine the final risk list of the project through risk identification; The risk evaluation model is established, and the weight of each factor of the construction risk of A expressway elevated project is determined by using the fuzzy hierarchy method, and the construction risk of the project is evaluated quantitatively by using the fuzzy comprehensive method. It is concluded that the risk grade of the project is "high", that is, there are high risks in the project, and the quantitative evaluation results provide a strong basis for the guidance of the risk response strategy of the project, and on the basis of the risk evaluation results. In this paper, the risk countermeasures of A highway viaduct project are given, and the detailed countermeasures are worked out. The research in this paper can not only guide the risk management of the project, but also serve as a reference for the risk assessment of similar elevated projects.
