Seepage and Consolidation Analysis of High Earth-Rockfill Dam
Abstract The Nuozhadu high earth-rockfill dam is the highest earth-rock dam in China. Its seepage-consolidation characteristics are very representative of high earth-rock dams. A complete monitoring system was installed in the dam, and a great deal of field observation data have been obtained. In this chapter, the field observation data of pore-water pressure in the core wall of the Nuozhadu high earth-rockfill dam is first analyzed. Then, the finite-element program developed in this dissertation is applied to the analysis of unsaturated consolidation of the dam. Comparing the numerical results with the observation data, the reasonability of the results is proved, and the multi-physics coupling mechanism in the core wall of high earth-rockfill dams is explained. Moreover, the applicability of the theory and program established in this dissertation to the large-scale three-dimensional consolidation analyses of complex high earth-rockfill dams is also discussed.
