| 摘 要： | 随着交通事业的发展,预应力砼连续刚构桥以其施工简便、造价经济、受力合理、行车舒适等优势在近年来迅速崛起,在主跨200～300m范围内几乎成为首选桥型。但其理论和经验还不十分完善,在修建过程中也存在一些技术上的问题。以重庆忠县至垫江高速公路上高岩嘴特大桥主桥为例,阐述连续刚构桥中跨合拢时顶推力的计算方法,以及顶推后对该桥型受力性能的影响,供工程设计施工人员参考。

| Abstract: | With the development of traffic construction,the continuous rigid frame bridge has been growing up rapidly in recent years characterized with handy construction,economical cost,reasonable internal force and comfortable travelling.It almost has become the first selective bridge style when the main span is in the range from 200m to 300m.But the theories and experiences are not perfect.There are still several problems in the construction.Based on Gaoyanzui extra-long span bridge,the computation and accomplishment of jacking force of the continuous rigid frame bridge are introduced,and analyzed the performance of the bridge after jacked. |

| Keywords: | continuous rigid frame bridge closure jacking force performance after jocked |
