Conclusions and Future Work

Abstract

In recent years, with the growing social demand and the development of construction technology, earth-rockfill dams built in China are being built higher and higher. In high earth-rockfill dams, the seepage and consolidation behaviors of the clayey core wall are significantly different from those of low dams, showing apparent multi-physics coupling effects. These phenomena are difficult to reasonably explain and accurately simulate with previous theories and methods. Therefore, in this dissertation, on the basis of the previous studies, the mechanical properties of unsaturated compacted clayey soil, the multi-physics coupling consolidation theory, the numerical programming, and their practical engineering applications to high earth-rockfill dams are investigated. The main work and conclusions of this dissertation are as follows.
