| 摘 要： | ±500kV直流输电线路横穿整个青藏高原，其生存环境不可避免与冻土和不良冻土现象有紧密的联系。由于冻土具有冻胀、融沉特性及不良冻土现象等问题，因而，输电线路要安全运行，线路选线定位时就必须了解与线路有关的冻土工程问题。本文从影响输电线路选线定位的因素出发，在分析冻土输电线路工程问题的基础上，从多个角度建议了线路建设中的工程对策，为即将开工的±500kV青藏直流联网工程的顺利进行提供科学依据和参考。

| Abstract: | The ± 500kV direct transmission line across the Qinghai-Tibet plateau will be seriously affected by frost heaving and thaw settlement characteristics of permafrost. Therefore, in order to learn more about permafrost engineering problems, this paper analyzes the living environment and the influencing factors of transmission line, and studies the engineering problems, and then proposes the engineering countermeasure. These results can be used as a reference for supporting the project construction smoothly. |
