非洲马普托大桥基准索股精度控制方法

Accuracy Control Method of Datum Main Cable Strand of African Maputo Bridge

马普托大桥是非洲第一大跨度悬索桥,地处马普托湾和港口区,环境复杂,施工难度大,因此,必须有1个合理的基准索股精度控制方法,才能保证主缆索股架设。论文介绍了马普托大桥悬索桥基准索股精度控制及提高精度的相关方法。该方法是适用于海外大型悬索桥主缆架设控制的1种施工方法,希望通过论文给予海外悬索桥施工技术人员以借鉴。

Maputo bridge is the biggest suspension bridge in Africa, locates in Maputo bay and harbor, with complex condition,hard construction difficulty, so there must be a reasonable accuracy control method of datum main cable strand,to ensure the successful installation of main cable. This thesis introduces a method about accuracy control and improve the accuracy of datum main cable strand. It＇s fit for aboard large suspension bridge main cable control. May be a reference for future engineers working for aboard suspension bridge.
