多联现浇预应力连续箱梁桥同期施工问题探讨

摘要

回顾了现浇预应力连续箱梁桥施工近20年的发展概况,结合规范要求与设计经验,对满足桥梁多联同期施工所需要注意的问题进行了探讨,其研究结果对类似项目的设计、建造具有一定的借鉴意义。%A general situation for the 20 years development of synchronous bridge construction of cast-in place prestressed continuous box beam is presented in this paper.Based on the code requirement and design experience,several problems to satisfy bridge synchronous construction of multi-joint continuous beam is inquired.The result provides some help for design and construction of similar projects.
