摘　　要：新寨河特大桥为预应力混凝土连续刚构桥,箱梁施工悬臂长度大,为了确保主桥在施工过程中结构受力和变形始终处于安全的范围内,且成桥后的主梁线形符合设计要求,结构恒载内力状态接近设计期望,在主桥施工过程中应进行监控。监控主要针对桥梁位移、应力应变和温度三方面,监控效果较好。Xinzhai River Bridge is a prestressed concrete continuous rigid frame bridge and the construction cantilever of box girder is length. It is essential to have a monitoring in order to ensure security of force and deformation of the main bridge structure, girder shape with the design requirements and the internal constant - load forces of the structure close to the design during the construction process. Monitoring aimed at the bridge displacement, stress and strain and temperature have better result.
