山区高速公路因地形复杂,高填深挖路段较多,填方高度大于30m的路段经常出现,本文以某高速高填路段为例,进行设计方案研究比选。 Due to the complicated topography and high embankment and digging sections, the mountainous expressways frequently appear in the sections with a height of more than 30m. Taking a high-speed and high-loading section as an example, the design of the highway is studied and compared.
