| 摘 要： | 着重对河湾路基侵蚀机理进行了理论分析与试验研究。通过对弯道环流的形成，发展特性以及凹岸路基边坡泥沙运动规律及对路基侵蚀试验成果进行分析，发现凹岸路基的侵蚀主要是由河湾水流对路基边坡的淘刷以及路基的崩塌而引起，并提出了各种抵抗河湾路基侵蚀的防治措施。

| Abstract: | The erosion mechanism of highway subgrade along river bend is studied by using theory analysis and model tests.The analysis of the circulation flow creation,development features and subgrade slope sediment movement laws in the curved channel is made.It is found that highway subgrade erosion is resuired from the flow scouring and subgrade failure.Finally,the methods of subgrade protection along river bend are presented. |
