Forecasting of Concrete Dam Cracking Opening Based on Copy Theory

Sun Binbin;Yu Weiwei;Su Guannan;State Key Laboratory of Hydrology-Water Resources & Hydraulic Engineering,Hohai Univ.;National Engineering Research Center of Water Resources Efficient Utilization & Engineering Safety,Hohai Univ.;College of Water Conservancy & Hydropower Engineering,Hohai Univ.;  
The cracking on the long running concrete dam is affected by the environment stably but barely by aging;and there is some certain regularity among the monitoring data.Considering this fact,the method based on copy theory is adopted to analyze the dam cracking monitoring data.The data are able to be fitted and forecasted by resolving the original data series;and then fitting,restoring and reconstructing the resolved data.Taking the cracking data of a certain measuring point in Chencun dam for example,the fitting and forecasting results show a good effect,so as to prove the effectiveness and the applicability of the method.
