| Abstract: | For rapid increase of China urban traffic and great demand of urban traffic, in order to reduce damages of road construction to regional planning and influences on existing buildings, urban tunnel projects become new trend of development. Based on the connecting tunnels in Yuzhong of Chongqing, this paper introduces the relevant technologies for structural design of tunnel portals in connected bridges and tunnels to provide a reference for design of similar projects. |
