为了促进桥梁顶推法施工技术的发展,对目前桥梁建设中广泛应用的顶推法施工技术进行了综述,着重介绍和总结了顶推施工中导梁参数的确定方法、梁体施工精度对顶推过程产生的影响、梁体顶推过程受力分析、顶推过程中局部受力分析及改善措施、顶推法施工控制等研究成果。研究结果表明：多点顶推过程中的局部受力状态、施工误差对梁体局部受力的影响以及下部结构采用拉索加固法时的索力优化问题仍较为突出;研究指出了近几年在中国发展起来的步履式顶推施工法所存在的一些问题,探讨了今后顶推法施工的发展趋势。

英文摘要：

In order to promote the development of bridge incremental launching construction technology,the technology widely used in current bridge construction was reviewed.The method for determining key parameters of the launching nose,influence of beam construction accuracy on incremental launching process,force analysis of incremental launching process,force analysis of local stress and improvement measures and incremental launching construction control were introduced and summarized.The results show that the influences of local stress status in the process of multipoint incremental launching and construction error on bearing beam,and the optimization problem of cable tension when cable reinforcement method is used in substructure are still prominent.Finally,some existing problems on walking type incremental launching construction at present in China are mentioned and the further development trend of incremental launching construction is investigated.
