Design Method and Process of Overall Plan for Highway Bridge Reconstruction and Expansion under Multiple Constraints
With the increasingly perfect network structure of expressways in China,the construction focus will be further tilted towards the reconstruction and expansion of expressways.In addition,the construction period of existing expressways requires smooth operation,and there are many control factors in adjacent areas,making bridge reconstruction and expansion a key and difficult point in the reconstruction and expansion of expressways.Based on the requirements for bridge renovation and ex-pansion in the regulations,the design methods and processes for bridge renovation and expansion un-der multiple constraint conditions are formulated,and the renovation and expansion plans for highway bridges under multiple constraint conditions are explored through the expansion project of a highway with navigation and overpass triline high-speed rail,providing reference for similar projects.
