摘　　要：以穿越戈壁荒漠的红柳沟～若羌段的路基水毁调查为基础，提出了“淘底滑塌”、“冲蚀啃边”、“冲刷截断”3种主要的水毁形态，并概化成物理模型进行了水毁机理试验及防护试验研究，以探索戈壁公路路基水毁形成机理及水毁防护技术。通过大量的试验比较，提出了水毁路段合理的防护方案。分析表明，采用格宾箱体结构或格栅笼结构用于国道315线改建工程中的水毁防护工程，与传统的防护结构相比，具有较大的技术和经济优势。The patterns of damage from other regions, because of the geology. Based on the survey of da , causes and mechanism of the damaged roadbed in G315 road is also different characteristics of climatic conditions, topography, the geological and hydrologic maged roadbed from Hongliugou to Ruoqiang across the desert, it was concluded three major damage patterns, that is ＂the bottom of slippery and disrepair＂; ＂erosion gnaw＂ and ＂erode section＂. It is generalized into physical model to research the water damage mechanism and protection project tests, so as to explore the mechanism of damaged roadbed and the protection technology in Gobi highway. Through testing and analysis and comparing with the traditional protective structure, it shows that box cabinet structure or grating cabinet structure have larger technical and economic advantages in the damaged protective works in G315 road.
