摘　　要：推导了连续刚构桥中跨合龙时合龙顶推力的解析公式,并以河耳沟特大桥为例,介绍了连续刚构桥顶推力的计算及实现.The analysis formula of jacking force is deduced when the mid-span of a continuous rigid frame bridge is in closure. Based on Heergou extra-long span bridge, the computation and accomplishment of jacking force of the continuous rigid frame bridge are introduced.

关 键 词：连续刚构桥 合龙 顶推力
