Large-deformation finite element analysis of the interaction between concrete cut-off walls and high-plasticity clay in an earth core dam

摘要

Purpose - A large, uneven settlement that is unfavourable to dam safety can occur between a concrete cutoff wall and the high-plasticity clay of earth core dam built on alluviums. This issue has been often studied using the small-strain finite element (FE) method in previous research. This paper aims to research the interaction behaviour between a concrete cut-off wall and high-plasticity clay using large-deformation FE analyses.
