Survey and evaluation of the unfavorable geological phenomena of high voltage transmission line engineering in high altitude mountain area and countermeasures——take Sichuan-Tibet networked power transmission and transformation project as an example
The Sichuan-Tibet Internet-connected power transmission and transformation project,which was put into operation in 2014,connects Tibet Changdu power grid with Sichuan power grid,which is in the southeast of Qinghai-Tibet Plateau,a region with a high occurrence of geological disasters in our country.The adverse geological phenomena in the region through which the project line has passed are extremely developed,which brings great difficulty for the choice of line scheme and the location of power tower.The network project adopts various investigation methods and countermeasures in different stages of investigation and different types of adverse geological processes to reduce the impact of adverse geological processes on the project.
