【摘要】：高海拔地区电网建设面临着自然条件恶劣、生态环境十分脆弱的情形,与普通地区电网建设项目技术存在较大的差异,对于其周围地区在经济、社会以及自然环境所产生的作用和影响十分显著；同时高海拔地区电网工程项目的后评价具有重大的政治、经济和社会影响。如何充分评估高海拔地区电网项目运行后的技术、环境、经济和社会效益,并科学合理地对项目进行后评价,为提高今后项目建设的决策水平提供可靠的支撑成了十分重要的研究课题。本文通过对高海拔地区大型电网建设项目后评价的内涵及特点进行深入分析后,对施工效果、技术、环境和人身保障措施的先进性、适用性、安全性进行详细的分析,研究提出了适合高海拔地区电网工程项目后评价体系和模型,并在此基础上对青藏电网联网工程项目进行后评价。高海拔地区大型电网建设项目后评价内容主要包括以下5部分内容：(1)高海拔地区电网建设项目施工效果后评价。通过对施工环境,尤其是冻土特性及其对工程影响的分析,对高海拔地区大型电网建设项目的施工方案进行对比,分析总结建立高海拔地区电网建设项目施工效果后评价的指标体系,并验证其合理性。(2)高海拔地区电网建设项目环境影响后评价。通过分析高海拔地区电网工程施工对环境的影响、容易引发的环境问题以及保护环境的主要措施,建立高海拔地区环境影响后评价指标体系,并通过实证分析其有效性。(3)高海拔地区电网建设项目技术后评价。针对高海拔地区电网工程项目技术的特殊性,分析工程项目面临的主要技术问题及技术解决方案,建立高海拔地区技术评价指标体系,通过实证对其有效性进行验证。(4)高海拔地区电网建设项目人身保障后评价。对高海拔地区施工的特殊性以及其主要面临的人身安全问题进行研究,提出了一系列保证施工人员人身安全的方案,并建立了相应的施工人员人身保障效果后评价指标体系,并进行了实例分析。(5)高海拔地区电网建设项目综合评价。本部分通过对施工效果、环境影响、技术、人身保障、社会经济效益等进行综合评价,得出青藏联网工程的电网建设项目具有良好的实施性及有效性。
[Abstract]:The construction of power grid in high altitude area is faced with the situation that the natural conditions are bad and the ecological environment is very fragile. There is a great difference between the technology of the power grid construction project in the ordinary area and the surrounding area in the economy. The effects and effects of society and the natural environment are very significant. At the same time, the post-evaluation of high-altitude power grid project has significant political, economic and social impact. How to fully evaluate the technical, environmental, economic and social benefits after the operation of the high-altitude power grid project. And scientific and reasonable post-evaluation of the project. In order to improve the decision-making level of project construction in the future to provide reliable support has become a very important research topic. This paper deeply analyzes the connotation and characteristics of post-evaluation of large-scale power grid construction projects in high-altitude areas. The construction effect, technology, environment and personal security measures are analyzed in detail, and the post-evaluation system and model suitable for high-altitude power grid project are proposed. On this basis, the post-evaluation of the Qinghai-Tibet power network project is carried out. The content of post-evaluation of large-scale power grid construction project in high-altitude area mainly includes the following five parts: 1). Post-evaluation of construction effect of power grid construction project in high altitude area. In particular, the characteristics of frozen soil and its impact on the project analysis, the high-altitude area of large-scale power grid construction project construction projects are compared. This paper analyzes and summarizes the index system for the post-evaluation of the construction effect of the power grid construction project in the high altitude area. And verify its rationality. 2) the environmental impact assessment of high altitude power grid construction project. Through the analysis of the impact of power grid construction on the environment in high altitude area. Easy to lead to environmental problems and the main measures to protect the environment, the establishment of high-altitude environmental impact assessment index system. And through the empirical analysis of its effectiveness. 3) the post-evaluation of power grid construction project technology in high-altitude area, aiming at the particularity of power grid project technology in high-altitude area. The main technical problems and technical solutions faced by engineering projects are analyzed, and the technical evaluation index system of high altitude area is established. Through the empirical verification of its effectiveness. 4) the post-evaluation of personal security in high-altitude power grid construction project. The particularity of construction in high-altitude area and the main personal security problems are studied. This paper puts forward a series of schemes to ensure the personal safety of the constructors, and establishes the corresponding evaluation index system of the personal security effect of the constructors. The comprehensive evaluation of the power grid construction project in high-altitude area is also carried out. This part evaluates the construction effect, environmental impact, technology, personal security, social and economic benefits, etc. It is concluded that the grid construction project of Qinghai-Tibet interconnection project has good implementation and effectiveness.
