Abstract:

The Liuyuan-Golmud Expressway is built in the Hexi Corridor and the inland extreme arid area of Qaidam Basin. Along the route, alpine wind-sand is the main environmental feature. Currently, there is limited research on the sand processes and prevention along the Liuyuan-Golmud Expressway. Therefore, through field observations and particle size analysis, this study investigated the wind-sand environment along the highway and found that the prevailing winds are from the northwest (NNW、WNW、W), with frequency of sand-driving wind, sand transport potential, and maximal possible sand transport higher occurring in the summer months (May to July). In contrast, these factors are lower in the winter months (November to January of the following year). The sand transport direction along the highway primarily trends towards SE、SSE、ESE and E. From north to south along the highway, the surface sediment particles transition from fine sand to coarse sand, with the average particle size gradually becoming coarser. The particle distribution is relatively uniform, with fewer coarse particles.

Key words: alpine wind-sand environment, Liuyuan-Golmud Expressway, wind dynamic environment, sand transport potential, particle size analysis
