2-D Non-Linear Finite Element Analysis Of Folsom Dam: Seismically Induced Separation And Pore Pressure Along The Soil-Concrete Interface, Grace Amoussou
Master of Science in Civil Engineering Theses
The seismic soil-concrete interface stability of composite dams has been an area of interest to many researchers. However, the true interface behavior during a seismic event has not been well understood. During a ground shaking, bonding and de-bonding action along the interface may cause significant separation of soil and concrete surfaces, and such a separation may take place at any depth along the interface creating a stability concern for the overall dam. Moreover, the repetitive nature of bonding/debonding behavior may induce excess pore pressure along the interface, which in turn, may trigger a liquefaction failure or a hydraulic fracture in …
