摘　　要：针对某钢混组合连续梁桥顶推施工,分析了使用的监控技术方法,确定了主梁线形及应力监控测点布置方式,明确了桥梁顶推施工监控要点。施工监控结果表明,该桥各项指标的监测值与设计要求吻合,主梁线形及应力状态均控制在合理范围内。Taking a steel-concrete composite continuous beam bridge as the background,in this paper the monitoring technology and methods used in the incremental construction process of the steel-concrete composite continuous beam bridge are analyzed,the main beam alignment and stress monitoring measurement point and layout are determined,and the key points of bridge incremental construction monitoring are defined.The construction monitoring results show that the various monitoring indicators of the bridge are consistent with the design requirements,and the main beam geometry and stress state are controlled within a reasonable range.
