Abstract： In view of the river-related underground space tunnel and viaduct construction project， due to the complex surrounding environment and high traffic pressure， relying on the reconstruction project of the section from Laoyuhang to Wuchang sections of National Highway 235 in Hangzhou， through the temporary transformation of the river， the design concept of coplanar structure of bridge and tunnel is put forward. In this paper， a construction technology for reducing the settlement of river-crossing bridges and tunnels in soft soil area is developed， which can be used as a reference for similar projects.

Keywords： wall pier; joint construction of bridge and tunnel; relocation; pile foundation; soft soil area
