摘　　要：对宝珠寺大坝17号和22号坝段顺流向水平位移监测资料进行统计回归分析,得到模型的回归方程及各影响分量,同时使用挠度理论公式验证了其中水压分量的精度。此分析方法对于重力坝变形监测模型中水压分量的精度校验、乃至确定相关项目的监控指标,有借鉴和参考意义。Regression analysis on the horizontal displacement monitoring data ot clam secnons No.17 and No. 22 of Baozhusi dam is carried out. The regression equation and influence components are ob- tained. At the same time, the accuracy of hydraulic pressure component is verified by application of de- flection theory formula. The analysis method can be used for calibration of the hydraulic pressure compo- nents in deformation monitoring model for gravity dam, as well as for the determination of monitoring in- dexes for similar projects.
