现浇连续梁桥是目前被广泛采用的一种桥梁结构形式,它一般分为现浇连续梁和现浇连续刚构两种形式,跨径从20m～40m不等,2孔～4孔为一联,一般采用桩柱式下部结构,上部采用空心板或箱梁形式,配筋分为预应力和非预应力两种。由于连续梁桥具有线形舒展、伸缩缝少、刚度大、行车平稳、养护简便等优点,对于跨径变化大、曲线复杂的城市立交来说,有着其他结构不可替代的优越性,成为城市桥梁工程的首选结构型式。
Cast-in-situ continuous girder bridge is widely used as a form of bridge structure, which is generally divided into two forms of cast-in-situ continuous girder and cast-in-place continuous rigid frame. The span ranges from 20m to 40m, A joint, the general use of the pillars of the lower structure, the upper hollow plate or box girder form, reinforcement is divided into two kinds of prestressed and non-prestressed. As the continuous beam bridge has the advantages of linear stretch, fewer expansion joints, high rigidity, smooth running and convenient maintenance, etc., it has an irreplaceable superiority to the urban interchange with large span and large curve. It has become an urban bridge project The preferred structure type.
