Abstract

This paper presents a series of finite element analyses aimed at investigating the influence of dam geometry, which in turn depends on the valley shape, on the settlement behavior of rockfill dams. The validity of the analysis method is verified with the well-instrumented case. All computed results show that the dam geometry, especially in narrow canyons, plays an important role in the dam settlement behavior. The evidence is interpreted through a modified valley shape factor S β proposed in this study taking into account the abutment slope, which provides a more rational approach to gain insight into the effect of valley shape. © 2019 Elsevier Ltd
