Dynamic dam-foundation interaction is great important in the design and safety assessment of dam structures. Two classic boundary conditions, i.e., viscous-spring viscous boundary, are employed to consider radiation damping unbounded rock foundation. The input models seismic excitation derived. accuracy two conditions dynamic analysis foundation verified through using an impulsive load. influen...

Along with the development of virtual reality (VR) technology, simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. This paper presents a Virtools-based visual simulation method and realizes a concrete dam pouring process. It proposes that the mode of the dam for a certain period could be...

In this study, the elastic modulus of cemented sand and gravel (CSG) dam its dependence on confining pressure were clarified by performing triaxial compression tests pressuremeter tests. The results these material verified a reproduction analysis dynamic behavior Apporo Dam during an actual earthquake. By analyzing 30 seismic records dam, characteristics clarified. New findings obtained regardi...

Because of different behavior of reservoir water and dam material, the determination of hydrodynamic pressure during earthquake is very complicated. Thus, different formulations have been presented for modeling of the dam reservoir system under dynamic loading such as earthquake. These formulations can be categorized into two general groups, which are Lagrangian and Eulerian, each having advant...
