雪害地段路基施工技术

公路雪害作为影响公路交通安全的重要因素，是我国降雪较多的西部地区公路施工中需要重点解决的问题。通过分析公路路基风吹雪害的类型、形成条件以及造成的危害，对其防治技术进行了探讨。结合S229线吉木乃至黑山头路段以及S319线吉木乃至吉木乃口岸公路改建工程中雪害处理的施工经验，详细介绍了雪害路段的公路路基施工技术，可以为类似工程项目建设的开展提供合理的参考。

Technology of Subgrade Construction in Snow Disaster Zone

Snow damage is an important factor affecting road safety and it is a key issue which needs to be solved in highway construction in western China with heavy snowfalls. This paper analyzes the types, for-mation condition and harm of drifting snow disaster of highway subgrade and also brings out the preven-tion and control measures. Combines with the construction experience in the reconstruction project of Ji-munai and Heishantou segment of S229 Line and Jimunai to Jimunai Port segment of S319 Line, this pa-per introduces the highway subgrade construction technology at snow disaster zone in detail and it can pro-vide reasonable references to construction of similar engineering projects.
