Sheltering effect of punched steel plate sand fences for controlling blown sand hazards along the Golmud-Korla Railway: Field observation and numerical simulation studies

Sand fences made of punched steel plate (PSP) have recently been applied to control wind-blown sand in desertified and Gobi areas due their strong wind resistance convenient situ construction. However, few studies assessed the protective effect PSP fences, especially through field observations. This study analyzes effects double-row on using observations a computational fluid dynamics (CFD) numerical simulation. The results showed that average windproof efficiencies first-row second-row were 79.8% 70.8%, respectively. Moreover, simulation behind 89.8% 81.1%, sand-resistance efficiency was 65.4%. deposition occurred close fence; however, there relatively little leeward side fence. length accumulation near obtained by basically consistent with observations, indicating combined can provide insight into complex over fences. indicates protection is sufficient for effective hazards associated extremely areas. output this work expected improve future application
