Analysis of displacement observation data of a concrete dam
According to the displacement observation data of a concrete dam from 2013 to 2019,based on the qualitative analysis of the variation law of dam crest horizontal displacement and its various influ-ence components,the reliability of observation data is further analyzed,the stepwise regression model of displacement observation values is constructed,and the impact of the upstream water level,temperature and time effect is quantitatively studied.In addition,the automated measurement by tension wire align-ment is compared with the manual measurement by collimation line,and the reason for their differences is analyzed,providing reference for the evaluation of dam displacement behavior.
