Open full text 0 citations

Abstract

Heel is a critical area due to the high-gradient when the stress of a concrete gravity dam is analyzed. This article employed ANSYS, a kind of structure analysis software, to establish a two-dimensional model and to analyze the stress of a concrete gravity dam with Finite Element Method. Then the effects of upstream slope ratio on the stress of the dam heel in the operating conditions were researched and some valuable conclusions drawn from this paper can be adopted by the designer of concrete gravity dam.
