Abstract

The observation of horizontal displacement is one of dam safety inspection items,the 27 locations were observed by collimation line method in Luopoling reservoir dam.Regression analysis of horizontal displacement were simulated by statistical model based on observation data,the model has better precision.Finally,change rule of dam horizontal displacement and the main factors of water level,atmospheric temperature and aging effect affecting dam displacement were studied.
