Abstract：Shield method has become the main construction method for urban subway construction due to its advantages of high automation,high efficiency and low disturbance,but the influence on neighboring buildings is still unavoidable.Combined with the actual project,three-dimensional finite element modeling was used to analyze the influence of the subway shield tunnel lateral crossing a large barrage in this paper.At the same time,the power boundary and train operation load were applied to the model to consider the impact of the subway operation on the barrage.The results showed that,the shield tunnel boring construction had little influence on the close lateral crossing the barrage under the support of reasonable construction reinforcement and construction technology.And the dynamic loading of vehicles during the camping phase had less influence on the barrage.This study can provide suggestions for the safe construction of projects,as well as provide a reference for the design of similar projects.
