摘要
本文以石家庄北三环(原石太高速)跨越南水北调干渠节点工程为例,通过正交、斜跨、原位改造等几种不同的主辅路线位方案及斜拉转体、变截面连续梁等不同的桥梁工程结构类型组合,研究市政工程项目跨越南水北调干渠的可行性,为北三环市政化改造提供专项技术支撑,研究经验亦可作为类似南水北调相关项目的参考。
This paper takes Shijiazhuang North Third Ring Road(formerly Shi-Tai Expressway)crossing the South-to-North Water Diversion node project as an example,through several different main and auxiliary alignment schemes such as orthogonal,diagonal span,in-situ transformation,and different combinations of bridge engineering schemes such as diagonal span,variable section continuous beam,etc.,to study the feasibility of municipal engineering projects crossing the South-to-North Water Diversion,providing special technical support for the municipalization of the North Third Ring Road,and the research experience can also be used as a reference for similar The research experience can also be used as a reference for similar South-to-North Water Diversion related projects.
