A fully coupled non-linear dynamic analysis procedure and its verification using centrifuge test results

摘要: The equations governing the dynamic behavior of saturated porous media as well a finite element spatial discretization these are summarized. A three-parameter time integration scheme called Hilber–Hughes–Taylor α-method is used together with predictor/multi-corrector algorithm, instead widely Newmark's method, to integrate spatially discrete equations. new possess quadratic accuracy and desirable numerical damping characteristics. proposed solution bounding surface plasticity theory describe constitutive behaviour soil have been implemented computer code DYSAC2. Predictions made by DYSAC2 verified using centrifuge test results for clay embankment. Importance initial state on its demonstrated.
