  要:路线设计是公路工程设计的基础和灵魂。旧路改建工程由于其自身特点,实施过程中所出现的设计、施工问题多且技术复杂,合理的路线设计对缩小工程规模、减小工程投资、降低施工难度等方面均起到决定性作用。本文结合绛帐至汤峪公路改扩建工程的设计实践,提出路线线形设计一般做法及优化措施,以期为改扩建项目设计工作提供参考。

Abstract: Route design is the basis and soul of highway engineering design. Due to the inner characteristics of highway reconstruction projectnumbers of complex designing and constructing problems appears during the constructing process. Therefore, reasonable route design plays a vital role in minimizing engineering scalereducing project investmentand lowering construction difficulty. Combining with the designing job of Jiangzhang to Tangyu Road extension projectthe common practice and optimizing measurement in alignment was put forward by the writer in the hope of providing reference for the designing of reconstruction project.
