悬索桥基准丝股线形的确定与测控

Determination, Measurement and Control of Datum Wire Strand Geometry of Suspension Bridge

介绍了润扬长江公路大桥悬索桥基准丝股线形在温度和跨度变化时的修正计算方法,提出采用影响系数的办法来修正温度和跨度变化的影响,以方便施工和监理的应用;探讨了悬索桥基准丝股线形的控制测量方法。

This paper presents the calculation method for modifying the datum wire strand geometry of the Suspension Bridge of Runyang Changjiang River Highway Bridge under temperature and span variations, proposes that the temperature and span variation effect should be modified with influential coefficient method in order to facilitate construction and construction supervision, and also discusses the methods for measurement and control of the datum wire strand geometry.
