经济在发展,社会在进步,促进了公路工程项目的增多,而路基支挡工程是建设公路的基础。但现阶段对路基支挡工程设计形式的研究还比较少。本文将从陡坡路基下部支挡工程、深路堑路基支挡工程等方面对路基支挡工程设计形式进行相关阐述,希望对相关参与者与研究人员带来一定帮助。 Economic development, social progress, and promote an increase of road projects, and subgrade support project is the basis for building roads. However, at this stage, the research on the design form of subgrade retaining engineering is still relatively small. This article will elaborate the design forms of subgrade support engineering from the support engineering of the steep slope subgrade and the support project of deep cutting subgrade, and hope it will bring some help to the relevant participants and researchers.
