Abstract:

The Baotou-Lanzhou Railway is the first railway in China to cross the desert, among which the Shapotou section suffered from the most severe aeolian sand hazard. The protective system is vital to the construction and safe run of this railway. Based on literature comprehensive analysis of the protective system of Shapotou section of the Baotou-Lanzhou Railway during the last 60 years, we summarized the research results from the sand-fixing measures and their efficiency, the structural characteristics of the protection system, and the design of reasonable width. At present, the ecological environment in this area is fragile, and there are some problems in part of the area, such as the deterioration of soil moisture conditions, the degradation of artificial sand-fixing vegetation, the damage of measures of sand drift control, and the extensive development of sandy patches caused by wind erosion. Finally, we proposed corresponding strategies and future research priorities, which could provide a scientific reference for the maintenance, improvement and sustainable management of the protective system.

Key words: Baotou-Lanzhou Railway, protective system, sand-fixing measures, structural characteristics, protecting efficiency
