摘要
沙漠高速公路建设在西部大开发中的战略地位和重要作用，决定了高速公路风沙防治已成为保障交通安全的主要内容之一。本文以陕西榆靖沙漠高速公路为例，通过对本区风沙运动规律及榆靖沙漠高速公路沙害治理条件的综合分析，提出以固、阻、输、导、拉、抬等手段，定向控制风沙蚀积，人为促进风沙流及沙丘的转化。
Express highway plays a strategic and important role in the western development movement. Sand control, therefore, has been a major task in the construction of express highway in sand ＆ wind --stricken area. The paper takes Yulin--Jingbian express highway as a case to analyze the sand and wind movement along the express highway as well as the integrated conditions for sand control. The measures such as fixing, blocking, conveying, leading, pulling and raising, ect. Have been developed to alleviate the sand erosion and divert movement of sand dunes.
