Abstract: In the early storage period, the control of reservoir rise rate is an important issue for deformation and stability of the core wall. By analysis of the monitoring data on deformation and seepage in different parts of the core wall, conclusion was obtained that the fast rise of reservoir level would cause larger deformation of the core wall, and the deformation of core wall would reduce the effective stress of soil. With the effect of reservoir water, seepage may occur because of hydraulic fracturing.
