Study on protection effect and optimization of emergency sand control measures for Geku Railway
摘要
Abstract
The hazard of wind driven sand has always been the main factor affecting the safe of railway in sand areas.In order to study the effectiveness of emergency sand-prevention measures for Geku-railway,the timeli-ness of the existing protection system and the emergency measures required after the failure of sand fences are studied based on wind tunnel experiment and numerical simulation.The results show that the existing protec-tion system can intercept most of sand grains in the initial stage of use.However,and the sand grains can pass over the sand protection system to form sediment accumulation on the windward after using for a period of time.The track sand accumulation can be significantly reduced by installing emergency sand control measures on the windward side.Comparing the amount of sand accumulated in the sand collector under different emergency measures,the solid emergency sand fence has the least amount of sand accumulated,the porosity of 60％has the most amount,and the 15％and 30％porosity emergency measures are in the middle.The increase in po-rosity of emergency sand fence does not have a good sand prevention effect.After setting up pores at the top 1/3 of the solid sand fence,the road area sand accumulation is reduced by about 20％,38％and 56％compared to the solid,the fences with porosity of 15％and 30％,respectively,achieving a better protective effect.关键词
