摘      要：Large dams are complex structures with nonlinear dynamic *** often are forced to assess dam safety based on the available incomplete data,which is extremely *** important problem can be solved with the modern theory of complex *** is possible to derive characteristics of the whole unknown dynamics of a structure using few data sets of certain carefully selected representative parameter(s).By means of high quality continuous records of some geotechnical characteristic(s)of a dam and modern methods of time series linear/nonlinear analysis the main dynamical features of the entire,unknown process(here—dam deformation)can be *** created the cost-effective Monitoring Telemetric System for Dam Diagnostics(DAMWATCH),which consists of sensors(tiltmeters),terminal and central controllers connected by the GSM/GPRS Modem to the diagnostic *** tilt data recorded for varying reservoir level are compared with static design model of dam deformations computed by a finite element method(FEM)for the dam-reservoir-foundation ***,recently developed linear/nonlinear data analysis and prediction schemes may help to quantify fine dynamical features of the dam *** software package DAMTOOL has been developed for this *** differences between measured and theoretically predicted response parameters of the dam may signal abnormal behavior of the *** data obtained already by testing of the DAMWATCH/DAMTOOL system during operation of the high Enguri arc dam and reservoir(Georgia)show interesting long-term and short-term patterns of tilts in the dam body,which can be used for dam *** proposed real-time telemetric monitoring(DAMWATCH)complex and linear/nonlinear dynamical analysis system(DAMTOOL)are unique.
