摘要
Abstract
Taking the inconsistent data of the horizontal displacement of the dam of a hydropower project in the southwest as an example,the abnormal situation was analyzed in terms of the accuracy and performance of the instrument,meteorological elements,instrument verification parameters,and the accuracy of the calculation process.The results show that the trend of the horizontal displacement of the dam top in the direction of the river mainly results from the systematic error caused by the change of the monitoring parameters of the instru-ment.During the period of abnormal data,the addition and multiplication constants of the verification were positively increased compared with those in 2016,resulting in an increase in the length correction.As the working base points of the dam monitoring are located on the slopes on both banks upstream,the dam shows a trend of horizontal displacement downstream along the river,but the overall variation is small and there is no abnormal change.关键词
