Combining with some continuous rigid bridge project along Nanchuan-Daozhen Expressway,the paper illustrates the factors in the clo-sure process of the bridge,analyzes the relationship between the pier top deviation and jacking push of the bridge,and deduces the calculation process of the jacking push,so as to provide some reference for the closure construction of similar bridges.%结合重庆南川至贵州道真高速公路某连续刚构桥工程实例，阐述了该桥型合龙过程中所受到的影响因素，分析了桥梁墩顶偏位与顶推力之间的关系，并推演出相应的顶推力计算过程，为今后类似桥型的合龙施工提供了参考。
