摘要
针对由于挠度监测数据的漏测造成监测数据的不完整性,结合曾家沟大桥工程实例,通过采用MATLAB计算软件,采用拉格朗日内插法对拱桥钢拱架施工时的挠度监测数据进行插补并分析,从而完善该桥挠度监测数据。
Aiming at the imperfection of the measurenaent data resulted from the missed measurement of the deflection measurement data, combining with the project of Zengjiagou large Bridge, the author gets the interpolation analysis in the steel arch construction of the arch bride on adopting the MATLAB calculating software and the Lagrange interpolation, thus perfecting the measurement data of this bridge.
