Abstract:The overall scheme for the Changsha G319 (Leifei Avenue - Yongtong Road) Project is studied. The current conditions along the route are deeply analyzed, the relevant upper-level planning is interpreted, and through traffic demand prediction analysis, the construction scale of the project is reasonably determined. Combined with the construction conditions, it is determined to adopt a combined construction form of partial continuous elevated sections combined with ground sections and node overpasses. The regional road network is comprehensively considered, and the main and auxiliary entrances and exits as well as interchanges are reasonably arranged. Under the premise of ensuring the operation safety of the high-speed rail, the reasonable technical measures are taken to pass through the railway. The research results and process can provide reference for similar projects in Changsha in the future.
