摘　　要：针对涉河地下空间隧道和高架路桥建设工程,因周边环境复杂,场区交通压力大,依托235国道杭州老余杭至五常段改建工程,通过河道临时改迁,提出桥隧共线共面结构设计理念,研发一种软土地区涉河桥隧合建减沉施工技术,为类似工程施工提供借鉴。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.
