库布齐沙漠穿沙公路工程防沙体系维护技术

The Maintenance Techniques for the Sand PreventionSystem Along the Highway Crossing Kubuqi Desert

库布齐沙漠穿沙公路两侧现有工程防沙体系破损情况日趋严重。调查显示,工程防沙体系破损的主要形式是风蚀、沙埋和材料的腐烂,体系破损具有不等时性、不等量性、不均匀性和效益的残留性。在此基础上,制定了防沙体系风蚀、沙埋破损程度的鉴别标准,并针对体系不同的破损形式、原因、程度提出了相应的维护技术,供公路养护部门参考。

The engineering sand prevention system along the highway of crossing Kubuqi desert was damaged seriously. Investigation indicated that the wind erosion、sand burying and material corrosion were the main problems.the system damaged in different time、to different quantity、and unevenly, but remained some of benefit.On the basis of that,we formulate a judging standard for wind erosion and sand-burying degree of sand -preventing system. Moreover the different maintenancetechnologies were put forward according to the different damage form、cause and degree of the system.It can serve as reference to maintaining highway.
