高速公路的修建工程中,路基是修建高速公路的基础,也是尤为重要的一个环节,路基施工的质量水平与安全系数直接决定着整个高速公路的施工质量。高速公路施工过程中,保障路基的强度与稳定性,十分的重要,但是随着社会的高速发展,高速公路的扩建规模也在逐渐扩大,路基施工受到了来自各个方面的影响,众多问题也逐渐的凸显出来,本文通过对高速公路路基开挖及填筑施工进行了深入的分析,以望解决高速公路路基施工中出现的种种问题。 In the expressway construction project, the subgrade is the foundation of the expressway construction and also a particularly important link. The quality level and safety factor of subgrade construction directly determine the construction quality of the expressway. In the course of highway construction, it is very important to ensure the strength and stability of roadbed. However, with the rapid development of society, the scale of expressway expansion is also gradually expanding. Subgrade construction has been affected by all aspects, and many problems have also gradually taken shape Of the highlights, this paper through the highway subgrade excavation and filling construction conducted in-depth analysis in order to solve the highway subgrade construction problems.
