Analysis on Bridge and Tunnel Co-construction Mode and Engineering Design Technical Characteristic
Taking Jiaxing Expressway Loop Line engineering and Yiwu Airport Road interchange reconstruction engineering as examples,this paper focuses on the analysis of different forms of bridge and tunnel co-construction in river system,so as to solve the problem of ground and underground road traffic crossing the river system in the same location without affecting flood control and navigation.Combined with their own characteristics and construction conditions,the Changshui Road Tunnel on Jiaxing Expressway Loop Line and the Phase Ⅲ Tunnel on Yiwu Airport Road have adopte d different co-construction modes of"upper bridge and lower tunnel",which has reference significance for solving similar traffic construction problems.
