Abstract

Abstract: Based on the meteorological station statistical data from 1955 to 2014 and field observation data along Gerlha section of the Qinghai-Tibet Railway, this paper studied the characteristics of wind energy environments in terms of wind direction, gale days and sand-dust storm days, sand drift potential and decadal variations of annual mean wind speed, and demonstrated their impacts to railway sand hazards. Mono wind direction, relatively high wind energy environments and the sand hazards going worse were our conclusion. This research has important meaning in monitoring the sand hazards developing trends and improving sand control system along Qinghai-Tibet Railway. It also can be a good reference for the design of other highway and railway sand control system which pass sandy regions as well.

Key words: Qinghai-Tibet Railway, sand hazards, wind energy environments
