Elasto-Plastic Dynamic Finite Element Analysis of an Earth-Rockfill Dam
Advances in Soil Dynamics and Foundation Engineering, 2014The Pastor-Zienkiewicz-Chan model based on the generalized plasticity theory can simulate the stress-strain relationship of soils quite well. Based on the triaxial tests of the filling materials of an earth-rockfill dam, model parameters were obtained through fittings of model and test data.

Study on Seismic-spectrum Characteristics for 300m-grade Earth-Rockfill Dam
2010 Asia-Pacific Power and Energy Engineering Conference, 2010Combining with Shuangjiangkou Dam with height of 312 m, we make a study on the spectrum characteristics of rockfill dams with core wall adopting the dynamic model which reflects vibration-hardening character of coarse rockfill materials. The rationality of the model and parameters is verified by comparing calculated values with measured values of ...

Back analysis of earth rockfill dam's seepage property based on cloud reasoning
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010For the aim of reflecting the randomness, fuzziness and the relevance between the two existed in the back analysis of earth rockfill dam's seepage property, by assumption of normal cloud distribution of the seepage parameter, a new back-analysis method based on cloud reasoning is presented in this paper.

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 ...

Static Behaviour of Earth — Rockfill Dams
1991Fill dams (or embankment dams) were the first dams built by man, they are the most numerous and the most frequently chosen when it is a question of constructing a new dam. According to Penman (1986), in 1985 statistics showed that over 80% of the large dams (higher than 15 m) constructed in the world were earth dams.

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.

Advanced Materials Research, 2011
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 ...
