因受地形限制，山区公路经常出现高填深挖的情况，因此路基病害也较多。通过G320曲靖-昆明段和G108元谋-武定段路基病害的深入调查，根据山区公路路基病害的特点，对山区公路路基病害进行了分类，并系统分析了病害的成因。对调查路段存在较多的路基横坡破坏进行了分类，分别分析了其形成原因。探讨了研究路基横坡破坏的意义。

Highway in mountainous area, due to landform limitation, is often in the circumstances of high fill and deep cut, resulting in many subgrade diseases. Through the deep investigation on the subgrade diseases in the G320 Qujing-Kunming Section and the G108 Yuanmou-Wuding Section, they are classified according to their characteristics and the genesis is analyzed systematically. In addition, lots of cross slope failures of the subgrade existed in the sections investigated are classified and the causes analyzed respectively as well. At last, the meaning of the study on cross subgrade slope failure is discussed.
