Experimental study on the sand control effectiveness of combined PE net and reed barriers along railways in sandy areas
摘要
Abstract
Wind-sand hazards are one of the primary threats to the safe operation of railways in sandy regions.To evaluate the sand control performance of different sand barrier combinations,this study systematically ana-lyzes the wind reduction and sand control effects of various layouts of PE net and reed barrier through wind tunnel experiments and numerical simulations.Results show that a single row of reed barrier can reduce wind speed by up to 45％,significantly outperforming the 32％reduction achieved by a single row of PE net.A double row of reed barrier forms a stable low-velocity zone between the structures,with wind speed reduction exceeding 60％,demonstrating better wind control than double PE net.Among combined barriers,the"flexi-ble front and rigid rear"configuration(PE net-reed)exhibits the best sand control performance,the total sand transport rate is about one-third of that with the single PE net.Under high wind speeds,this configuration maintains effective wind reduction and sand deposition regulation,forming a multi-stage protection mechanism of disturbance-deposition-stabilization.It offers a promising approach for enhancing wind-sand hazard control in railway systems across sandy regions.关键词
