Simulation of creep deformation of faced rockfill dam based on secondary development of ABAQUS

Abstract

The creep deformation of concrete face rockfill dam is one of the key factors affecting the safety and performance of a concrete faced rockfill dam. In this paper, creep deformation process was carried out by secondary development based on ABAQUS software. A concrete faced rockfill dam in Laos is the research object of long-term deformation inversion. The calculated results are in good agreement with the measured analysis results. The proposed method can provide reference for the long-term deformation of earth-rockfill dam.
