锚索张拉千斤顶标定值与测力计读数误差分析

Calibration of anchor rope stretching jack and reading error analysis of dynamometer

通过洪家渡水电站的天生桥料场锚固工程,比较分析试验锚索测力计与油表读数关系,同时对测力计与千斤顶油表进行标定,对两系统的误差原因进行试验分析,为锚索的张拉提供更准确、更合理的施工参数。

At the anchoring project of Tianshengqiao construction material yard for Hongjiadu Hydropower Plant, the readings from anchorage rope dynamometer and oil gauge were compared and analyzed; the dynamometer and jack oil gauge were calibrated at the same time; test and analysis were conducted to clarify the reasons for error of two systems, so that more accurate and more rational construction data is available for thestretching of anchorage rope.
