Abstract:

This study focuses on wind-blown sand problems along highways, reviews the development history, current situation and characteristics of highways in sand region, and systematically summarizes wind-blown sand damage and achievements of sand control in China's sandy highways, according to wind-dynamical environments along highways, sand damage characteristics, disaster-causing mechanisms, wind-blown sand prevention and control measures along highway, structural composition and benefits of sand-control system. Considering that the drifting sands environments on both sides of the highway, gobi surface and the regional differences in natural environments, while taking into account the sand controlling, green corridor construction and landscape efficacy, and ensuring the continuous stability and functional perfection of road protection systems in sandy areas, three representative sand-control mode have been systematically sorted out to ensure the continued stability and functional perfection of the protection system for highways in sandy areas. Based on the practical needs of the increasing improvement of highway network skeleton system and the challenges of safe operation of highways in sandy areas, the focus is on strengthening the engineering and technical foundation of highway wind-blown sand control and improving the capacity of blown sand hazards control, and condensing and proposing the future research focus and development trend of sandy roads.

Key words: highways in sand region, wind-blown sand damage, sand-control measures, wind-blown sand control system
