Abstract:

Auto-regression method, based on the variation of monitoring points, allows us to illustrate the correlation among the shifting value of the monitoring point throughout observed circles.. The paper is applied the auto-regression to establish the model, test the quality of the model using the statistic correlation, and predict the movement of observed points in dam of Yaly’s hydropower plant. Experimental analysis suggests that the auto-regression method is a good solution for prediction the tendency of movement monitoring. The difference between the predicted value and the measured value of two cycles over 6.2% and the smallest is 1.7% of the actual measurement value. Hence, the autoregression method can meet the requirement of prediction for soil and rock dam of hydropower plants in Vietnam
