ABSTRACT

Based on the 330kV transmission line project of Yushu and Qinghai main network, the characteristics of temperature changes along the line were analyzed in this paper. The transmission line crosses the permafrost section, and the engineering geological conditions of permafrost are complex and sensitive to environmental warming. Based on the temperature observation data of Gonghe station, Maduo station, Qingshuihe station, Xinghai station and Yushu station from 1960 to 2010, the regional temperature changes were analyzed. The results show that the temperature in the permafrost area along the transmission line has gradually increased in fluctuation for nearly 50 years, which will lead to changes in the permafrost environment. Furthermore, the temperature changes will have a certain impact on the stability of the 330kV transmission line permafrost area project of Yushu and Qinghai main network.
