摘　　要：作为广东省首条山岭重丘区高速公路改扩建项目,汕梅高速公路改扩建项目旧路技术指标低,控制因素多,施工期间不能中断交通,改扩建技术难度大。桥涵改扩建方案对结构安全、交通组织、施工工期、工程造价有显著影响。针对既有桥涵特点与改扩建技术难点,对山岭重丘区高速公路改扩建桥涵设计原则、拼宽方案、设计要点进行了研究和总结,对类似项目建设具有指导和借鉴意义。As the first expressway reconstruction and extension project in the mountainous and hilly areas of Guangdong Province,Shanmei Expressway reconstruction and extension project faces many challenges,such as low technical standards of the old road,numerous control factors,and the requirement to maintain traffic during construction.The reconstruction and extension plan of bridges and culverts has a significant impact on the structure safety,project cost,traffic organization and construction period.Considering the characteristics and challenges of the old bridges and culverts reconstruction and extension,this study investigated and discussed the design principles,bridge widening schemes,and the key technical points for the design of expressway bridges and culverts reconstruction and extension in mountainous and heavy hilly areas,which provides a valuable reference and guidance for similar projects.
