浅谈改扩建项目中纵断面动态设计

Brief Analysis on Vertical Section Dynamic Design in Rebuilding and Expanding Project

以河北省石家庄至磁县(冀豫界)公路即京港澳高速石家庄至磁县(冀豫界)段高速公路改扩建项目为例,重点介绍在设计过程中的纵断面动态设计,总结出纵断面动态设计的必要性、特点及难点,以对以后的高速公路改扩建项目的动态设计提供一些启示。

Take Shijiazhuang - Cixian （ Jiyu boundary） highway, in other words, Jing - gang - ao highway Shijiazhuang- Cixian（ Jiyu boundary）highway rebuilding and expanding as example, focus on introducing vertical section dynamic design in design process, and concluding necessity, characteristics and difficulties of vertical section dynamic design, providing reference for future highway rebuilding and expanding project dynamic design.
