Taking the close-distance side penetration viaduct pier foundation of the shield tunnel of some subway section as the example,the pa-per adopts the finite element software to establish the calculation model,analyzes the displacement of the bridge pier,points out the calculation results are within the permitted value of the deformation control of the viaducts,the shield tunnel can be safely side penetrated into the viaduct pier according to the feedback information and accurate adjustment shield parameter under the inspection of bridge deformation.%以某地铁区间盾构隧道近距离侧穿高架桥桥台桩基为例，采用有限元软件建立了计算模型，分析计算了桥桩的位移变化情况，指出计算结果均在高架桥变形控制的允许值内，在不采取辅助加固措施下，通过监测桥梁变形情况，并根据反馈信息及时精准调控盾构参数，盾构隧道可安全侧穿高架桥桥台桩基。
