Abstract: Regression analysis on the horizontal displacement monitoring data of dam sections No.17 and No. 22 of Baozhusi dam is carried out. The regression equation and influence components are obtained. At the same time, the accuracy of hydraulic pressure component is verified by application of deflection theory formula. The analysis method can be used for calibration of the hydraulic pressure components in deformation monitoring model for gravity dam, as well as for the determination of monitoring indexes for similar projects.
