- Abstract:
- In order to solve the problem that ordinary dam was easily damaged by boulders in debris flow, a selfcentering dam was proposed, and steel ball was used instead of large debris flow stone. The new type debris flow dam was simulated under the impact of large debris flow stones by using finite element software ABAQUS. The analysis of comparison between the self-centering dam and ordinary gravity dam was made on deformation, reaction force, displacement and acceleration. The results show that compared with the ordinary gravity dam, the selfcentering dam has superior impact resistance and its stress distribution is more homogeneous and smaller than ordinary gravity dam. The reaction force and acceleration are much smaller than the ordinary gravity dam, but the displacement is slightly larger than the ordinary one.
