Abstract Abstract：Research purposes： Golmud-Korla Railway passes through the Tarim Basin, goes through the Taklimakan and Kumtag Desert with G218 National Highway and Tarim River. Taitema Lake area through the Golmud-Korla Railway is located in a low-lying sediment transportation channel from Kumtag Desert to Tarim Desert, and the railway crosses the wind-sand flow area where the desertification is serious, the construction of the railway and subsequent operations will be affected by the wind-sand flow, the project could also have an impact on the traffic capacity of G218 National Highway. Therefore, choosing the appropriate engineering means to pass the serious wind-sand flow area is the focus of the study. Research conclusions： Through analyzing the characteristics of wind-sand flow and environment geological conditions of the section of Taitema Lake where the railway passes through, on the basis of the full collection and analysis of a large number of sand data, the project settings should meet three requirements: (1) to dredge sand and should not set up sand blocking project; (2) reducing the impact on the environment and can't aggravate the impact of sand on the G218 National Highway; (3) the operation maintenance is relatively easy in operation period. The bridge program to pass through and control the clearance of the bridge could meet these conditions after comparing the three types of engineering of roadbed, bridge and tunnel. This case provides a good reference for future multi-program research and demonstration in the construction of railways which on the basis of the full collection and analysis of a large number of data in serious adverse geological area.
