摘　　要：高陡路堑段路基拼宽、调曲线常用挡墙、桩板墙、桥这3种方案,每种方案又有多种形式可以考虑。道路设计施工技术人员的工作就是根据现场具体的地质、地形条件,开动脑筋,努力创新,通过技术设计和经济分析,选取合适的方案,将天堑变坦途。经研究,采用基础梁工字钢挡墙方案,现场施工简单快捷、施工工期节约、施工成本有效降低、同时保证了施工期的质量和安全、降低了后期维护难度。There are three common schemes for roadbed widening and curve adjustment in high and steep road sections:retaining walls,pile sheet walls,and bridges.Each scheme has multiple forms to consider.The job of road design and construction technicians is to select appropriate solutions based on the specific geological and topographical conditions of the site,through technical design and economic analysis.After research,it has been found that using the foundation beam I-beam retaining wall scheme,on-site construction is simple and fast,construction period is saved,construction costs are effectively reduced,while ensuring the quality and safety of the construction period and reducing the difficulty of later maintenance.
