摘　　要：桥梁顶升技术最早应用于国内为20世纪50年代,主要用于铁路桥梁的架设、位移和落梁。随着液压技术的发展,2003年9月,由计算机控制的液压同步顶升技术首次应用于桥梁的整体顶升。在新的一轮城市高速发展中,原市政桥梁常常遇到净空不够或原桥梁需与新建桥梁顺接等问题,利用桥梁顶升技术对城市高架进行改造具有良好的应用前景。The earliest application of bridge jacking technology at home was in the 1950s,which was used for the erection,displacement and girder falling of railway bridges. With the development of hydraulic technology,the computer-controlled hydraulic synchronous jacking technology was first applied for the overall jacking of bridges in September 2003. In the new round of urban high-speed development,the original municipal bridges often have problems such as enough headroom or the connection between the original bridge and the new one. The use of bridge jacking technology has a good application prospect for urban elevated transformation.
