摘要
从水流对路基的淘刷和路基崩塌2方面介绍公路河湾路基的侵蚀类型,分析沿河路基的侵蚀机理,阐述两者之间的关系。在此基础上用侵蚀形态试验得出河流侵蚀的特点,为合理处理河湾路基的侵蚀问题提供参考。
In this paper, types of corrosion to riverside expressway sub- grade are introduced from the 2 aspects in wash - off of sub - grade by water flows and in sub - grade collapses, mechanism of corrosion to riverside sub -grade is analyzed, the relationship between the 2 aspects is described. Based on this and through dynamic corrosion tests, the corrosion characteristics of river flows are summarized, and references are given for reasonable solutions to corrosion problems of the riverside sub - grade.
