摘　　要：地铁隧道施工必将穿越大量既有桥梁,并对其正常使用造成不利影响,桩基的变形是隧道下穿既有桥梁施工影响的控制核心。以莞惠城际铁路隧道下穿惠州市鹅桥施工为工程背景,通过现场实测数据分析隧道下穿既有桥梁的影响。Construction of subway tunnel will inevitably pass through a large number of existing bridges and make adverse impact to their normal use, among which the deformation of pile foundation is the control core during the subway tunnel construction passing through the existing bridges. Taking Guanhui Intercity Subway Tunnel passing through E Bridge in Huizhou City as an engineering background, on the basis of field testing data, the influence of subway tunnel passing through the existing bridges has been studied and analyzed.
