Abstract:

Gobi is a typical arid desert landscape and a major surface type along road in sandy regions. Influenced by underlying surface properties, surface material composition, and sand source reserves, the aeolian dynamic mechanisms and the focus of sand hazard prevention priorities in road engineering differ in gobi regions. This study delved into the differences in near-surface wind dynamics and aeolian transport processes between gravelly gobi surface and sandy-gravelly gobi surface. It systematically summarized the research progress on sand disaster prevention and control in road engineering in gobi regions, focusing on the characteristics, formation mechanisms, protective system, and their effectiveness evaluation of the two types of gobi sand hazards along road engineering routes. It also reviewed the main sand control measures and their applications in gobi road engineering. The sandy-gravelly surface, being a latent potential sand source with a mixed distribution of sand, gravel, and powdery sand layers, made it essential to strengthen the study of aeolian processes on sandy-gravelly surfaces. This helped ensure road safety and enhanced transport capacity in the gobi regions of the western China.
