Under the dual-carbon background

the ultra-high-voltage transmission line carries the important mission of power transmission and consumption of large-scale wind and light new energy power generation bases in the west.Geotechnical engineering investigation is an important link in the construction of ultra-high-voltage lines. Summarizes and discusses some issues involved in the whole process of UHV line engineering of western China

such as sorting out the investigation ideas

investigation workload layout

loess geological hazards

salinized soil diseases

bad geological effects such as landslides

karsts

and uneven foundations.
