张槐互通式立体交叉方案选型研究

Selection of Zhanghuai Interchange Schemes

张槐互通为新旧G108相交的不完全互通,在方案设计中受到村庄、工厂、县道和铁路跨线桥等诸多控制因素制约,布设条件复杂。在综合考虑上述制约因素的基础上,提出两个互通立交方案进行比选,最终提出安全、经济、合理、可行的方案,为类似互通的互通选型与匝道布设提供参考。

Zhanghuai Interchange is an incomplete interchange where the new and old Highway G108 intersect,with a complex alignment condition as it is constrained by multiple control factors such as villages,factories,county roads,and railroad crossings in the design process.Comprehensively considering the above constraints,this paper compared two interchange schemes and selected a safe,economical,reasonable,and feasible scheme,providing a reference for the selection and ramp alignment of similar interchanges.
