我区分布有大面积沙漠,占全国沙漠面积的一半以上。流沙除造成对农牧业生产的影响外,对于交通运输也有很大的危害。特别是沙漠边缘及其内部,随着国民经济事业的发展及战备的需要,公路建设也正在加速进行。因此,征服公路流沙危害,是我国西北干旱地区急待解决的课题之一。 My area is divided into a large area of ​​desert, accounting for more than half of the country’s desert area. In addition to the impact of quicksand on the production of agriculture and animal husbandry, there is also a great harm to transport. Especially at the edge of the desert and its interior, with the development of the national economy and the need for combat readiness, highway construction is also accelerating. Therefore, to conquer the dangers of highway quicksand is one of the urgent issues to be solved in the arid areas of northwest China.
