摘　　要：随着桥梁保有量的增加,桥梁老化和损坏的问题日益显著。为了确保桥梁的长期稳定和安全,老旧桥梁需要进行改造。以青岛青兰高速公路的肖家1号大桥为例,探讨了桥梁顶升改造施工的关键技术,重点分析了施工中的难点和应对策略。研究结果表明,针对桥梁病害、不良地质、紧张工期和海洋气象等问题,需要采取多层次的社会交通保障和施工保障措施,以及严谨的施工监控方法。With the increasing number of bridges,the issues of aging and damage have become increasingly significant.To ensure the long-term stability and safety of bridges,old bridges need renovation.Using the Xiaojia No.1 Bridge on the Qinglan Expressway in Qingdao as an example,this paper discusses the key technologies of bridge jacking renovation,focusing on the construction challenges and coping strategies.The study results show that for issues such as bridge diseases,poor geological conditions,tight schedules,and marine meteorological conditions,it is necessary to adopt multi-level social traffic and construction assurance measures,as well as rigorous construction monitoring methods.
