摘　　要：阐述了松原龙华松花江特大桥半刚构连续箱梁施工中临时水准点的设置与复测。主桥箱梁在悬臂施工过程中,必须设置高程控制观测点和施工临时水准点,以此作为全桥高程控制的基准,控制悬臂浇注时梁块的标高,确保全桥合拢后各点标高值符合设计要求。实践证明,龙华松花江特大桥成桥后的线形和合拢精度均达到施工规范的要求。This paper elaborated on the resuming measurement of the temporary level spot of the construction altitude control of half rigid frame continuous box girder. In the construction, temporary level spot and the height control observation spot should be settled as the standard of the height control of whole bridge, It controlled the scale height of gauge block to make sure the scale height of each spot of the bridge after folded fit the design requirement. Practice results proved that the closure precision and the alignment of bridge after being folded reached the demands of the construction criterion.
