预应力连续箱梁设计要点

Design Gist of Pre-stressed Continuous Box Girder

随着我国交通事业的发展,建造了大量的公路、市政桥梁及地铁区间高架桥梁,其中预应力连续箱梁占了不小的比例,量大面广的预应力连续箱梁直接关系着我国交通网络的安全畅通和有效服务。介绍了预应力连续梁的设计要点,有关经验可供相关专业人员参考。

With the development of transportation in China,a large number of highway,municipal bridge and metro elevated bridge are constructed,in which there is the high proportion of pre-stressed continuous box girder.The large number of pre-stressed continuous box girder is directly related to the safe,smooth and effective service of transportation network in China.The article introduces the design gist of pre-stressed continuous girder.The relative experience can be referred for the similar projects.
