摘要
Abstract
For the first time,a hybrid asymmetric span arch concrete bridge with thrust steel tube is adopted,which is beautiful in shape and novel in structure,and fully considers the coordination with the environment.The design and calculation of the bridge show that the design of the concrete filled steel tubular arch bridge can adopt light floating bridge deck system structure,concrete frame pier with greater self-weight,and appropriate foundation pre-eccentricity and increased foundation quantity to solve the problem of difficult reinforcement caused by greater horizontal thrust.The conclusions provide references for solving the problem of the greater horizontal thrust of this king of bridge and for the design of urban landscape bridges in the future.关键词
