现代化桥梁工程的特点是,工厂化、装配化、机械化和预应力化。目的是以最少的人力、最高的效率、最快的速度、最优的质量修建工程。当代桥梁,多以模数系列(按规律地将尺寸分级,组合搭配。)将桥梁分解为大小部件生产,促使预制工艺也相应发展。 Modern bridge engineering is characterized by industrialization, assembly, mechanization and prestressing. The goal is to build the project with the least amount of manpower, the highest efficiency, the fastest speed and the best quality. Contemporary bridges, mostly modular series (according to the size of the regular classification, combined with.) The bridge is broken down into small and large parts production, prompting the prefabrication process is also a corresponding development.
