摘要：

It is crucial to alleviate the effect of construction of underground transportation on the safety of the bridges in tunnel excavation region since it is inevitable for the tunnel to go across the city viaduct. To solve above problem, a technique of bridge reinforcement was proposed, which combines the jacking superstructure of bridges and grouting substructure. With this technique, the uneven settlement of the bridge foundation could be controlled as well as the change of the upper structure of bridges could be limited in a reasonable interval. Finally, the effectiveness of proposed method is demonstrated by reinforcing a real bridge in the region of subway construction in Guangzhou, China.
