南疆铁路吐鱼段风沙活动规律研究
Study on Wind-blown Sand Activity Characteristic at Turpan-Yuergou Section of Southern Xinjing Railway
摘要
Abstract
This paper observed and researched the characteristic of wind-blown sand activity in Gobi strong wind zone along the Southern Xinjiang Railway. The observation and research results show that:( a) There is obvious seasonal variation characteristic of strong wind in this zone, and each spring is the peak season of strong wind;the annual average number of the days with strong wind reaches up to 136d. ( b) The sand quantity carried by strong wind presents an obvious vertical distribution trend; there is a negative exponential correlation between sand quantity and wind height, and the higher the wind height rises, the smaller the sand quantity will be;the height range less than 2m is the key range where should be especially protected against sand hazard, because within this range, the sand quantity carried by strong wind accounts for about 96 percent of the total sand quantity carried by strong wind. ( c) Sand size grading experiment shows: there is obvious stratification phenomenon in the wind-blown sand movement in Gobi, and 0.1 to 0.25mm grain sizes are the main grain sizes.关键词
