路基是公路工程的重要组成部分,应具有足够的强度和稳定性,路基质量的好坏会直接影响到路面的整体质量,所以对其各个阶段施工中存在问题的了解与研究也显得尤为重要。根据公路填方段路基下沉的具体情形,结合现场施工经验,从处理方法、施工方法中的开挖、回填、挡墙砌筑等方面进行分析,并针对性地提出了公路施工中安全、文明、环保等方面所能采取的保证性措施,以期能够在此基础之上推进公路填方段的施工进度及保证施工质量,为公路顺利施工提供一定层面的参考、借鉴。
Subgrade is an important part of highway engineering. It should have sufficient strength and stability. The quality of the subgrade will directly affect the overall quality of the road. Therefore, it is particularly important to understand and study the problems in the construction of each stage. According to the concrete conditions of roadbed subsidence in the road filling section and the construction experience in the field, the paper analyzes the methods of excavation, backfilling and masonry retaining in the construction methods, and puts forward some suggestions on safety, Civilized, environmental protection and other aspects of the guarantee measures that can be taken in order to be able to promote the construction progress of highway fill section and ensure the construction quality on the basis of this, to provide a certain level of reference for the smooth construction of the highway, reference.
