3D Numerical Simulation of Elastoplastic Consolidation Process of Fly Ash Dam

Abstract:

The total consolidation process in the construction of hydraulic fill fly ash dam is calculated and analyzed by using the Biots consolidation theory and Cam-Clay model. Meanwhile, some problems such as characteristics of subsidence, excess pore pressure and stress of dam, influences coming from consolidation of hydraulic fill fly ash dam caused by drainage layer in dam foundation, etc, are analyzed. Results show that constructing hydraulic fill fly ash dam in saturated fly ash ground is feasible, and setting drainage layer in the dam foundation can greatly expedite the consolidation speed of dam, which is propitious to the safety of dam.
