国际上有关冻土地区输电工程建设的成功经验,对我国类似工程建设及相关问题的研究具有积极的借鉴意义.重点以加拿大育空地区和美国阿拉斯加地区输电工程为例,对国外冻土地区输电工程建设相关经验进行系统总结,涵盖工程建设全过程,即从工程前期准备到工程设计和建设直至工程建成后的运行维护.基于此,从完善工程评估机制、建立和执行相关工程建设规范与技术标准、工程建设环境风险控制以及确保工程运营安全等方面,探讨了国外经验的可借鉴之处.
The successful international experience in the construction of transmission projects in the permafrost region is of positive reference to the researches on similar projects in China and related issues. The emphasis is on the transmission projects in Yukon Canada and Alaska in the United States as an example. System construction and construction experience, covering the whole process of project construction, that is, from the preparation of the project to the design and construction of the project until the operation and maintenance after the completion of the project.On the basis of perfecting the project evaluation mechanism, establishing and implementing the relevant project construction norms and technologies Standards, environmental risk control of construction projects, and ensuring the safety of construction operations, etc., and explored the lessons to be learned from foreign experiences.
