马岭河特大桥8#主墩测量控制方法

摘要

马岭河特大桥是一座双塔双索面预应力混凝土斜拉桥，如何控制其主墩的施工精度以及精确定位斜拉索索导管是该桥施工的重点和难点。文章分析了该桥8#主墩的施工难点，提出了针对性的测量控制方法，并总结出能确保施工精度和有效缩短测量时间的相关经验。%Maling River Super-large Bridge is a dual-tower dual-cable prestressed concrete cable-stayed bridge,and how to control the construction precision of its main piers and to position accurately the stay cable conduits are the key and difficult point of its construction. The article analyzed the construction difficulties of the 8# main pier of the bridge, proposed the targeted measurement and control method,and summed up the relevant experiences to ensure the construction precision and to effectively shorten the measurement time.
