摘要

According to the typical Grew up longitudinal section of Ji cha highway operation safety problem, The Aizhai suspension bridge scheme and PaiBi extra-long tunnel scheme of route plan selection, Taken from the terrain condition, Plane scheme comparison and vertical control index study to reduce the average slope of large Crew up longitudinal, Balanced plane and longitudinal surface active measures of the index, In order to achieve the project safety, harmonious and integrated benefit target.%针对吉茶高速公路典型长大纵坡路段运营安全问题,通过对矮寨悬索桥明线方案与特长排碧隧道方案的路线方案比选,采取从地形条件、平面方案比选和纵面指标控制的研究来达到降低长大纵坡的平均坡度,均衡平纵指标的主动措施,以期达到项目安全、和谐的综合效益目标.
