摘　　要：为了充分发挥公路的使用功能及优化路网布局的作用,文章以某双向六车道高速公路改扩建项目为例,探讨了公路改扩建工程线形拟合设计的主要原则,包括安全第一、降低造价、改扩建道路与沿线设施协调、改扩建道路与路网协调等,分析了公路线形拟合设计所需的基础资料和实施步骤,并统计了样本差值,验证了线形拟合设计的准确性,以期提高我国公路改扩建项目的建设水平。In order to give full play to the use function of highway and optimize the layout of road network,this paper takes a two-way six-lane expressway reconstruction and expansion project as an example to discuss the main principles of linear fi tting design in highway reconstruction and expansion engineering,including safety fi rst,cost reduction,coordination between reconstructed and expanded road and facilities along the line,coordination between reconstructed and expanded road and road network.The basic data and implementation steps required for highway linear fitting design are analyzed,and the sample difference is counted to verify the accuracy of linear fi tting design,so as to improve the construction level of highway reconstruction and expansion projects in China.
