在高速公路的改扩建工程中,对于既有桥梁,若采用重建的方案,不仅造价很高,且需要中断部分交通,工期也较长。经检测研究认为既有桥梁的下部结构和上部结构完整、功能完好,仅需要进行整体加高、
Synchronized lifting of bridge becomes more and more common with the rapid development of transportation. A type of jacking system synchronously controlled by hydraulic pressure was introduced.It adopts industrial control computer,programmable controller and hydraulic control system to make up the distributed control system which is not only capable of synchronized lifting,but also can carry out real-time monitoring.This system has a broad prospect in projects of old bridge reinforcement and jacking.
