To Explore A Power Station Dam Safety Monitoring Data Processing Method

Dam deformation monitoring is monitoring the running status of dam engineering hiddendanger in the important day-to-day work, is the eyes and ears of the dam operationmanagement. In order to ensure the safe operation of the dam, according to "technicalspecification for concrete dam safety monitoring (DL/T5178-5178)," hydropower stationdam safety management regulations "(the state electricity regulatory commission of the thirdorder), the measures for the hydropower station dam safety monitoring work management(electric supervisor safety [2009] no.4) requirements, such as need for hydraulic monitoringof DAMS on a regular basis. In the on-site inspection in combination with regular monitoringdata on the basis of comparative analysis, etc, make a preliminary evaluation of the wholedam running, the protection of monitoring facilities, such as upgrading put forward opinionsand Suggestions. In order to grasp the avionics engineering sites, power plant, the workingstate of the ship lock operation period, verify the design parameters, and found the abnormalsituation to take timely measures, to ensure that the sites, power plants, ship lock can safelyrun normally, therefore, on the external deformation monitoring. Deformation monitoringwork included the monthly point measurement and the annual lighting control nucleus. Due tothe deformation monitoring point is on the basis of the control network to provide precisecoordinates, therefore is critical to control lighting nuclear work.Horizontal displacement of dam safety monitoring observation is one of the importantprojects. Combining power station dam crest Deal on11observation points with lock sidewall18observation points process, this research introduced the horizontal displacement of theline of sight observation method and the principle of forward intersection method, procedureand error analysis process that combines historial data on the horizontal displacementobserved data statistical processing, modeling and multivariate linear regression analysis, anddiscussed the water level, temperature and aging on the horizontal displacement of the degreeof influence and found the dam crest and lock the horizontal displacement by water level andtemperature effects had a marked impact of aging on the horizontal displacement is small, andthe use of second-generation method of partial least squares regression to re-establish thestatistical model, and multiple linear regression analysis to make a brief comparison andfound that partial least squares regression had better fitting effect than the multiple linear regression.This article mainly introduced the use of regression analysis and partial least squaremethod and two methods for the new power station dam locks on the point of measurementdata is analyzed, and carries on the comparison to the results of the analysis, can get thefitting results of partial least squares method is better, suggest after data-processing tend touse more analysis of the least-square method, the fitting result error is smaller, more accurateresults.
