Research on Choice of Dam Foundation Elevation in Hydropower Engineering
It is an important problem about how to choose an optimum foundation elevation of concrete gravity dam in the field of hydropower engineering design and geology engineering. In this research, finite element method was main tool and ANSYS software was used and we provided a practical method. Firstly, weak weathering layer was subdivided. Secondly, permeation condition, against slide stability condition, against pressure intensity condition and deformation condition should be fulfilled. At last, the elevation was confirmed. It is applied in a gravity dam and can be a valuable reference to other hydropower projects.
