Study on Design Methods and Technical Points of Rural Roads in Mountainous Areas with Small Traffic Volume

乡村振兴背景下,我国农村公路的建设规模和建设速度不断提升,但是农村公路的建设存在建设难度高、基础环境复杂的特点。结合案例调查法对一线案例展开深度总结,明确了农村公路建设的实际现状及其相关技术要求。结果表明,农村公路建设的纵断面设计、路基设计、路面结构基层设计以及排水安全设施设计是公路设计的重点。研究结论表明,选择合适的技术标准、平面线形指标以及地形地貌是保证高质量公路设计的关键,对此给出了相应的对策,可为我国农村地区的公路工程设计提供横向的参考和借鉴。

Under the background of rural revitalization,the construction scale and speed of rural roads in China have been continuously improved,but the construction of rural roads is characterized by high construction difficulty and complex basic environment.In this regard,this paper makes a deep summary of the first-line cases by combining the case investigation method,and clarifies the actual situation and relevant technical requirements of rural highway construction.The results show that the vertical section design,subgrade design,pavement structure base design and drainage safety facilities design of rural highway construction are the key points of highway design.The conclusion shows that the selection of appropriate technical standards,plane alignment indicators and terrain and geomorphology are the key to ensure the design of high-quality highways,and the corresponding countermeasures are given in this paper.The research content of this paper provides horizontal reference and reference for highway engineering design in rural areas of China.
