摘要
塔里木沙漠公路全长522km。，其中有四百余公里在塔克拉玛干沙漠中穿行，风沙危害十分严重。为了研究适合塔里木沙漠公路的防沙体系和防沙措施，从1991年起在塔里木沙漠公路两公里试验路段开展了公路防沙试验研究。1994年我们对两公里试验路段防沙体系中的各种防沙措施的防护效益进行了调查分析。通过分析可知：a塔甲木沙漠公路尽管风沙害严重，如果采用的防护措施得当，建立起外围阻沙、固沙和边坡防护相结合的防沙体系，是能够保证其正常运行的。b外围阻沙体可采取疏透型芦苇排栅栏或尼纶网栅栏，固沙带可采用碾压芦苇扎设草方格或带状沙障，有条件的地方最好与生物固沙结合；路基边坡最好采用LP高分子化合物固沙，非过沙断面可采用0.5×1m的芦苇草方格。
The length of Tarim desert highway is 522 km and over 400km of the road crosses the Taklimakan desert, windy and sandy harm is very serious there. In order to study system and measure of drifting sand protection of the Tarim desert highway, the author have developed the experiments of drifting sand protection of the desert highway on the Tarim desert highway with a length of 2km from 1991. Effects of various measures of coInbating drifting sand were investigated and analysised in l994. Result revealed that: (1)Although the tvindy and sandy harm is very serious, the highway can be prevent from drifting sand harm if the combating measures were chosen suitably. (2) Fence made by reed and nylon nets were buried in the periphery of the desert road that can be used for hinder drifting sand. Straw is half buried in line with local sand into checks to stabilize drifting sand. (3) Drifting sand on road bed can be fixed by using LP macromolecular compound.
