AbstractA consolidation analysis method for an earth-rockfill dam based on the coupling of physical state, stress deformation, and seepage was established. In this method, a permeability coefficient model considering physical state and shear stress level was introduced, and it was integrated with Biot’s consolidation theory to simulate the coupling ...

Dynamic Response and Mechanical Behaviours of Geogrid for High Earth-rockfill Dams
Geotechnical and Geological Engineering, 2021Due to the complexity of the interaction between the geogrid and the soil interface in high earth-rock dams, the method of replacing the grid with steel bars may neglect the interaction between the geogrid and the soil. The finite difference software FLAC3D is applied, and the geogrid element is used to simulate the geogrid and the coupling interface ...

Numerical analysis of the anti-seepage measures for high earth rockfill dam on deep overburden
Applied Mechanics and Materials, 2012The anti-seepage measures of a high earth rockfill dam built on the foundation with a deep overburden affects the stability and safety of the dam greatly. Nowadays there are few researches on this area both at home and abroad. On the basis of the finite element seepage analysis of the Pubugou high rockfill dam in which core walls and two cut-off walls ...

Considering the dynamic response of high earth-rockfilled dam, dynamic elasto-plastic analysis method for dam slope reinforcement with geogrids was set up. Based on this model, the paper analyzed the deformation and failure mechanism of dam slope, as well as the effect of connection, the length, the spacing and the stiffness of geogrid on dam with ...

Seepage and Consolidation Analysis of High Earth-Rockfill Dam
2018The 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.
