摘要
通过分析公路改建过程中旧路线形拟合技术、城镇化地段改线设计方法、公路局部改线设计方法及公路线形局部优化设计方法的特点,探讨了公路改建的线形设计过程需要注意的问题和处理措施,并结合具体工程实例进行了分析.该研究可为公路改建线形设计提供借鉴,并具有一定的工程实际意义.
By characterizing of old road alignment fitting technology and urbanization lot align- ment design method, local alignment design method and local optimization design method are analyzed, and problems and their treatment measures are discussed during highway reconstruc- tion process. Combined with specific engineering example, this article provides a reference for the highway reconstruction alignment design, has a certain practical significance in engineering.
