【摘要】：输电线路施工项目具有建设周期长、投资额度巨大、管控复杂等特点,使得在实际施工项目建设中存在多种不确定因素和风险。由于输电线路施工建设项目属于一次性建设项目,其建设和实施的过程要求极为严格,不容许出现建设失败的情况。所以,深入研究项目风险监管评价技术,明确的把握项目中存在的风险,并采用一定的监督和管理措施,使得风险降低到最小,才是务实之道,才能在尽可能在消除风险的同时,最大化的得到项目建设所带来的利益。本文从输电线路施工项目风险监管现状出发,首先研究输电线路施工项目风险监管评价体系,通过对输电线路施工项目中存的风险及特征的总结和梳理,提出了施工风险监管的五大要素,分别为施工成本、施工进度、施工安全、施工质量与施工环保,在此基础上,建立了风险监管评价指标体系；其次,对输电线路施工项目风险监管评价模型进行了研究,分别从指标权重的确定和模型的构建过程两方面展开了深入探讨,建立提出了基于模糊层次综合评价方法的输电线路施工项目风险监管评价模型；最后,采用我国南新110kV输变电施工项目对所提出的模糊层次综合评价模型进行了实例评价验证,得到了较为可信的风险监管评价结果,并对结果进行了深入的分析,从而实现了输电线路施工项目风险监管评价效能。综上,本文提出的输电线路施工项目风险监管评价模型具有良好的监管评价效果,且本文对输电线路施工项目的风险监管评价研究提出的分析方法、指标体系构建思路、评价模型以及案例应用等,对电力工程建设项目和其他施工建设项目都具有一定的理论与实践借鉴价值,为项目风险监管评价研究做出了贡献。
[Abstract]:Transmission line construction project has the characteristics of long construction period, huge investment amount, complex management and control, etc., which makes the construction of the actual construction project exist a variety of uncertain factors and risks. Because the construction project of transmission line is a one-off construction project, the process of construction and implementation is very strict, so the failure of construction is not allowed. Therefore, it is practical to study the project risk supervision and evaluation technology in depth, grasp the risk in the project clearly, and adopt certain supervision and management measures to minimize the risk. In order to maximize the benefits of project construction while eliminating risks as much as possible. Starting from the present situation of risk supervision of transmission line construction project, this paper first studies the risk supervision and evaluation system of transmission line construction project, summarizes and combs the existing risks and characteristics of transmission line construction project. Five elements of construction risk supervision are put forward, which are construction cost, construction schedule, construction safety, construction quality and construction environmental protection. On this basis, the risk supervision evaluation index system is established. The risk supervision and evaluation model of transmission line construction project is studied, and the determination of index weight and the construction process of the model are discussed. The risk supervision evaluation model of transmission line construction project based on fuzzy hierarchical comprehensive evaluation method is established, and finally, the fuzzy hierarchical comprehensive evaluation model is verified by using the new 110kV power transmission and transformation construction project in South China. The results of risk supervision evaluation are obtained, and the results are analyzed deeply, thus realizing the effectiveness of risk supervision and evaluation of transmission line construction projects. In summary, the risk supervision evaluation model of transmission line construction project put forward in this paper has good supervision and evaluation effect, and the analysis method and index system construction thought of the risk supervision evaluation model of transmission line construction project are put forward in this paper. The evaluation model and case application have certain theoretical and practical reference value for electric power engineering construction projects and other construction projects, and contribute to the research of project risk supervision and evaluation.
