黄龙特大桥主梁预应力管道摩阻系数试验研究

Study of Prestressed Pipe Friction Factor Test Base on the Huanglong Bridge' s Main Beam

本文在黄龙特大桥主梁预应力管道摩阻系数试验的基础上,采用油压传感器和电脑采样来实时测取千斤顶张拉力,简单易行,数据量大;并根据测量目标为常数而提出利用平均法来剔除异常和误差,使结果更逼近真值,为工程测试提供实用参考。

Based on the prestressed pipe friction factor test of Huanglong bridge＇s main beam, this paper＇s author take advantage of oil pressure sensor and computer for the real-time measure of jack＇ s tension, the practice shows that this method is simple, and can get large amount of reliable data. And according to the target of the measurement which is a constant, this paper uses the averaging method to remove anomalies and errors, it can make the result more close to the true value, so this method can provide practica~ reference for the engineering test.
