摘要
通过对国内多条已建成高速公路沟谷地形地段路基病害的调查,基于"沟谷"地形地貌特征与路基横纵填筑高度的差异和软弱地基强度的变异性特点,进行典型山区沟谷地形公路破坏、滑坡现象分析,以合理措施与动态信息指导路基施工,为路基结构的优化提供依据。
Through survey the number of domestic-buih vally terrain highway road subgrade disease , based on the＂ valley＂ topography of longitudinal and transverse roadbed filling height differences and weak foundation intensity variation characteristic of a typical mountain valley terrain highway damage, landslides phenomenon, with a reasonable measures Dynamic information and roadbed construction, the roadbed structure optimization provide reference.
