摘要
在桥梁施工过程中经常需要对桥梁墩台进行沉降观测。本文结合木瓜溪大桥墩台施工期间的多次沉降观测,讨论了桥墩台施工检测过程中控制网布设及其沉降规律,为较大型桥梁的施工提供较为科学的沉降规律。最后,用灰色系统模型对沉降监测点预测进行了探索,得出了一些有用的结论。
It is usually needed to survey settlement deformation of bridge pier in construction process. This paper comhines some settlement survey for many times of a big bridge piers in construction period, discusses the establishment of control network, and analyzes its settlement disciplinarian, which provides the science regulation for the bigger bridge construction. Finally, the settlement of the bridge is predicted using the grey model. Some useful conclusions are given.
