摘要
Abstract
With the large number of new bridges put into use, bridge detection and reinforcement technology has been paid more and more attention. Because of the large transportation volume and the high frequency of use, the bridge structures of urban rail transit lines are more prone to different kinds of diseases. Among them the damage of bridge bearing is particularly common. Synchronous lifting technology is currently the most commonly used technique for replacing bearings. The main principle is to carry out the savely lifting of the bridge superstructure through the synchronous control of jack. For the urban rail transit lines, the whole construction of replacing bearings must be finished without interruption or try to shorten the time of interrupting the traffic. So the construction technology of bridge bearing for urban rail transit needs more precise construction control.关键词
