顶升设备和顶升方式不同将对桥梁结构安全产生不同的影响。针对顶力同步顶升施工对桥梁结构的影响进行分析，结果表明：位移同步顶升对桥梁的不利影响远远小于顶力同步顶升，施工时应优先选择位移同步顶升设备，既可避免因顶升施工对桥梁结构造成损害，又可降低工程风险，提高施工效率。
頂升設備和頂升方式不同將對橋樑結構安全產生不同的影響。針對頂力同步頂升施工對橋樑結構的影響進行分析，結果錶明：位移同步頂升對橋樑的不利影響遠遠小于頂力同步頂升，施工時應優先選擇位移同步頂升設備，既可避免因頂升施工對橋樑結構造成損害，又可降低工程風險，提高施工效率。

Different jacking equipments and modes will produce different influences on bridge structures. This paper analyzes influences of construction in synchronous jack-up of jacking force on bridge structures, the results show that adverse influences of synchronous jack-up of displacement on bridges are much less than synchronous jack-up of jacking force, during construction synchronous jack-up equipments of displacement should be selected in priority, not only to avoid damages of jack-up construction to bridge structures, but also to reduce project risks and improving construction efficiency.
