全预制拼装技术在市政高架工程上的应用及思索

发展桥梁全预制拼装技术有利于节约资源、减少污染、提升生产效率,促进桥梁建设的工业化。受制于技术标准、工程造价和配套产业链等因素影响,市政高架桥梁建造方式仍以现场浇筑为主,坚持市场主导、政府推动和分阶段推进,力争到2020年使装配式市政高架占新建市政高架面积的比例达到30%以上。

Application and Thinking of Full Prefabrication Technology in Municipal Elevated Bridge Engineering

The development of the bridge full-prefabrication technology is beneficial to save the resources,decrease the pollutions,upgrade the production efficiency and promote the industrialization of bridge construction.Influenced by the technical standards,engineering costs and supporting industrial chains,the construction methods of municipal elevated bridge is still based onsite casting.The proportion of making the fabricated municipal elevated bridge account for more than 30%of the new municipal elevated bridge area by 2020 is strived by adhering to market dominance,government promotion and phase advance.
