【摘要】 针对浮动煤炭码头扩能改造项目中钢引桥受力发生变化的情况，需对原钢引桥强度重新验算，并对不能满足改造后的使用要求的部件进行加固补强。提出一种浮式煤码头桁架式钢引桥加固补强方案，在不拆除原钢引桥情况下，可确保该方案顺利实施。该方案可为同类项目改造工程提供施工技术指导。更多还原

【Abstract】 In view of the change of the force of the steel approach bridge in the capacity expansion and transformation project of the floating coal wharf, the strength of the raw steel approach bridge should be rechecked and calculated, and the parts that cannot meet the use requirements after the transformation are strengthened and strengthened.A strengthening scheme for truss steel approach bridge of floating coal wharf is proposed to ensure the smooth implementation of the program without dismantling the original steel approach bridge.This scheme can provide construction technical guidance for similar renovation projects.更多还原
