In order to improve the design efficiency of the high-speed railway bridge pier structural system and avoid low precision of the template design,the structural design method of bridge pier/pillar is optimized.The influence factors in the design of the template structure system are analyzed based on the relationship between the structure composition and the structure system.The mathematical model of the template structure design of high-speed railway bridge pier is established.The genetic algorithm is used to fulfill the optimal design of the template.The BIM model is employed as the template structure to design the mathematical model and assist the designer to develop automatically and visually the pier template structural system scheme.The example application verification shows that the template structure design method can effectively avoid the problem of inadequate design fineness of the bridge piers and pillars.After optimization,the structural mass is reduced by 37.9%,which reduces the influence of human factors in the traditional formwork design and effectively improves the design efficiency of the bridge piers and pillars.
