ABSTRACT
In this paper, rupture analysis of dam failure is given both by numerical analysis and physical model tests. For simulation of dam failure, numerical manifold method (NMM) and FEM are incorporated in elastic-plasticity analysis. A novel method of inserting cracks into 2D model mesh for 2D analysis with NMM. Tracing crack propagation in dam toe and heal is available and coincided well with those from physical rupture model. Re-mesh methodology for crack growth is related and proposed in this paper. Case studied for Jinping Arch dam is studied and a comparison of numerical and physical results is given in the last section of this paper.
