Use of models to study the stress state in a dam on a stratified anisotropic ledge-rock foundation

Abstract

Fairly detailed experimental and theoretical studies have been made of the effect of a ledge-rock foundation, regarded as an isotropic body, on the stress state of a large concrete dam [1-6]. However, in nature, in most cases, owing to fissuration, stratification, and other causes, ledge rock is anisotropic (or quasianisotropic). We are thus faced with the problem of studying the effect of anisotropy of a foundation on the stress state and stability of a structure.
