摘要
随着当地经济不断发展,为了提升路网干线运输通道作用,发挥路网整体效益有着重要意义。由于公路改扩建工程收原老路的许多限制,工程复杂、技术难度加大,根据以往的工程经验,展开了改扩工程路线设计原则、路线平面拟合设计、纵面拟合设计、平、纵面拟合组合与设计要点,提出了老路利用段以填方为主,同时结合工程案例对A线方案和E线比较方案进行了同深度对比,故同意该路段推荐采用E线方案进行分析探讨,为国内同类工程设计提供借鉴和参考,具有良好的工程实际意义。
work has great As the local economic development, in order to improve network main transport corridor, play net- significance to the overall efficiency. Due to the many limits to accept the original old highway re- construction project, the project is complex, technical difficuhy, according to the previous engineering experience, has launched A GaiKuo engineering route design principle, route plane fitting design, longitudinal surface fitting design, horizontal, vertical surface fitting combination and design key points, put forward the way to use paragraphs to fill is given priority to, at the same time, combining with engineering cases comparison on A line and E line scheme has carried on the contrast with depth, so agree with the E is recommended for the sections of line analysis, exploration to provide reference for similar domestic engineering design, has the good practical significance.
