Prediction of Hydro-mechanical Stability of Dam: Using Calibrated Model from Back Analysis and Monitoring Data
Abstract: Earth-fill dam
safety and stability control during service period is important at the view
point of economics and social security. Monitoring is very important to control
dam security, to compare real action with predicted planning and to make good
experience and opportunity for future planning. In this paper, water pore
pressure and settlements in different parts of Sattarkhan dam during service
period was studied. So at first, according to instrument data installed in the
body of dam, calibration of numerical model done and by doing back analysis
real properties of materials of dam defined. Then by using the calibrated
model, pore water pressures and settlements of dam studied. Analysis carried
out by Flac2D Finite Difference software. The constitutive model used was
Mohr-Coulomb at the state of plane strain. Results showed that dam will be safe
during service period at the view point of hydro-mechanical behaviour. Finally,
stability of dam studied from the view of rapid depletion of the reservoir,
which results showed safety conditions.
