近些年,随着我国经济水平的不断提高,国家对公路建设的重视程度也在逐渐的提高,尤其是对于黄土地区的公路建设,更加的重视。黄土地区的地形是比较复杂的,在黄土地区建设公路的难度比较大,若是无法保证公路的质量,不仅会造成巨大的经济损失,更会危害人们的生命安全。因此,在黄土地区建设公路必须重视其质量,公路质量与公路路基地基的承载力有着密切的联系。目前我国对公路路基地基承载力的研究还不够透彻,还不能有效的避免因地基承载力不足而导致公路出现质量问题的现象。因此,加强对黄土地区公路路基地基承载力评价方法的研究是势在必行的。
In recent years, with the continuous improvement of the economic level in our country, the emphasis placed by the state on highway construction is gradually increasing, especially for highway construction in the loess area. The topography in the loess area is relatively complicated. It is more difficult to build the highway in the loess area. If the quality of the highway can not be guaranteed, it will not only cause huge economic losses, but also endanger people’s life and safety. Therefore, the construction of roads in the loess area must pay attention to its quality, the quality of the highway and the bearing capacity of subgrade of highway are closely linked. At present, the research on the bearing capacity of highway subgrade is not thorough enough, and the quality problems on highway can not be effectively avoided due to the lack of bearing capacity of foundation. Therefore, it is imperative to strengthen the research on the evaluation method of the bearing capacity of highway subgrade in loess area.
