中国交通干线风沙危害防治模式及应用

公路和铁路是重要的陆地交通基础设施。我国风沙地区交通干线风沙危害的防治一直是国民经济和社会发展中的大事。针对我国风沙环境特征,面向铁路、公路安全运营的需求,我国开展了大量的交通干线风沙危害试验研究和防治实践,在防沙材料、防沙措施、防沙体系、维护管理等方面进行了系统创新,创建了4种不同风沙环境地区交通干线风沙危害防治模式,并在包兰铁路、青藏铁路、塔里木沙漠公路、准噶尔沙漠明渠等工程中得到成功应用。中国的交通干线风沙危害防治技术成果在世界干旱沙区尤其是"一带一路"沿线区域具有广阔的应用前景。

Patterns of Blown-sand Hazard Control for Traffic Arteries in China and Its Application

Highways and railways are important infrastructures of land transportation. The blown-sand hazard control of traffic arteries in sandy areas has always been one important issue in the national economy and society. In view of the characteristics of aeolian environment and the demand for safe operation of traffic arteries, China has carried out a large number of sand hazard control experiment and practices mainly on technology innovation of materials, measures, comprehensive system, maintenance, summed up four configuration patterns of sand control system, and created some patterns of sand hazard control technology for desert traffic arteries in different aeolian environments with Chinese characteristics, the patterns have been applied successfully in the Baotou-Lanzhou Railway, Qinghai-Tibet Railway, Tarim Desert Highway and Open Channel in Gurbantunggut Desert. China''s achievements in the sand hazard control for land transportation arteries have a broad application prospect in sandy areas in the world, especially in the countries along the Belt and Road.
