【摘要】：输变电工程是我国基础设施建设的重点之一,对于我国经济和社会持续发展起着重要作用。输变电工程建设过程后评价可以对工程建设期间的实际状态进行评价,为工程建设和改造提供指导和积累经验,促进项目可行性研究和前评价的客观公正性,有利于未来提高项目投资的科学化管理水平。本文通过对国内外建设项目后评价、建设过程后评价现状的研究,结合输变电工程项目的特点,详细探讨了过程后评价的相关问题,明确界定了输变电工程建设过程后评价的相关概念和内容。结合现有后评价理论和方法,以柳林-霍县500kV线路工程为研究对象,对其建设过程进行分析,并总结项目的前期工作—施工准备—建设施工全过程的实际结果。首先,采用熵权法与TOPSIS法对建设过程的前期决策和施工准备进行分析,通过与其它同一时段投产的3个同类工程进行对比分析,避免了纵向对比的片面性与局限性。其次,运用AHP与物元可拓模型,对建设过程的施工建设进行了研究。最后应用了逻辑框架法,定性分析了各个指标的实施水平,对工程综合情况等做了科学有效的评价,并根据评价结果对存在的问题提出了针对性的对策和建议。柳林-霍县500kV线路工程建设过程后评价体系的建立和综合评价方法的应用,为输变电工程建设过程后评价体系的制定提供了一定的科学方法,为同类工程的建设过程评价提供了一个有意义的探索。
[Abstract]:Power transmission and transformation project is one of the key points of infrastructure construction in China, which plays an important role in the sustained economic and social development of our country. The post-evaluation of transmission and transformation engineering construction process can evaluate the actual state of the project during construction, provide guidance and accumulated experience for engineering construction and transformation, and promote the objective fairness of feasibility study and pre-evaluation of the project. It will help to improve the scientific management level of project investment in the future. Based on the research on the post-evaluation of construction projects at home and abroad and the present situation of post-evaluation of construction process, combined with the characteristics of transmission and transformation projects, this paper discusses in detail the relevant problems of post-process evaluation. The concept and content of post-evaluation of transmission and transformation engineering construction process are clearly defined. Based on the existing theory and method of post-evaluation, this paper analyzes the construction process of 500kV line project in Liulin-Huo County, and summarizes the actual results of the whole process of the project from pre-construction preparation to construction. Firstly, entropy weight method and TOPSIS method are used to analyze the early decision and construction preparation of the construction process. By comparing with the other three similar projects in the same period of time, the one-sidedness and limitation of longitudinal comparison are avoided. Secondly, using AHP and matter-element extension model, the construction process of construction is studied. Finally, the logical frame method is applied, the implementation level of each index is qualitatively analyzed, the comprehensive situation of the project is evaluated scientifically and effectively, and the corresponding countermeasures and suggestions are put forward according to the evaluation results. The establishment of post-evaluation system and the application of comprehensive evaluation method in the construction process of 500kV line engineering in Liulin-Huo county provide a certain scientific method for the establishment of post-evaluation system in the construction process of transmission and transformation projects. It provides a meaningful exploration for the construction process evaluation of similar projects.
