Uplift and pore pressures are fundamental loading conditions that affect the strength and stability of concrete dams. Historically, these loads have been difficult to quantify and to implement in finite element analysis (FEA). Some dam design guidelines propose different techniques to apply the estimated uplift pressure for its use in FEA of concrete dams. These methodologies are, in general, q...

Abstract Seismic analysis of a fractured dam is generally complex problem. This paper presents an earthquake behavior investigation concrete gravity considering dam-reservoir--foundation rock interaction. The Koyna profile, located in India, adopted this study. nonlinear finite element analyses are conducted taking into account empty and full reservoir cases, to exhibit the hydrodynamic e ect w...

Abstract After the completion of Three Gorges Dam, it increases risk inducing an earthquake. We use GRACE Gravity Field Model to analyze relationship between operation Reservoir and change gravity field in western Sichuan. The research results indicate that reservoir water level Sichuan gravitational are positively correlated. In early stage rising level, is not apparent, gradually with time. T...
