Abstract

This paper describes a numerical investigation into the deflection of the upstream membrane of rockfill dams during reservoir impounding. The influence of the angle of the upstream slope on the subsequent deflection suffered by the concrete face slab is investigated. The procedure used for this investigation takes into consideration the gradual change between reloading and primary loading elastic modulus based on stress-state criterion.
