摘　　要：框构桥顶进施工邻近既有桥梁,为保证既有桥梁运营安全,需对框构桥顶进施工过程中对邻近构造物的影响进行详细分析和计算。以某市政路框构桥顶进施工为例,采用有限元法分析其对邻近铁路桥梁的影响,为同类工程提供借鉴。The jacking construction of frame bridge is adjacent to the existing bridge.In order to ensure the operation safety of the existing bridge,the influence on the adjacent structures during the jacking construction of frame bridge needs to be analyzed and calculated in detail.Taking the jacking construction of a municipal road frame bridge as an example,the influence on adjacent railway bridges is analyzed by the finite element method,so as to provide reference for similar projects.
