Stability of earth–rockfill dams: Influence of geometry on the three-dimensional effect
Computers and Geotechnics, 2005Abstract A series of parametric studies were performed to investigate the three-dimensional (3D) effect on the stability of an earth–rockfill dam, with respect to some major factors, such as geometrical characteristics of the dam and topography of the canyon. The length–height ratio of the earth–rockfill dam clearly influences the 3D safety factor. A

Research of Cloud Neural Network and its Application on Seepage of Earth Rockfill Dam
Advanced Materials Research, 2011 For the aim of being able to reflect the randomness, fuzziness and the relevance between the two existed in the seepage property of earth rockfill dam, by assumption of normal cloud distribution of the seepage parameter, a new back-analysis method based on cloud neural network(CNN) is presented in this paper, which has being used in the nonlinear ...

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 ...

Research on Analyzing Earth Rockfill Dam Seepage and Slope Stability
Advanced Materials Research, 2014Seepage damage has been one of the most important factors that affect the safe operation of embankment dams, So more consideration is taken into the saturated soil more than non-saturated soil. In this paper, we carry on the experiment by using SEEP/W software to take the flow field analysis of unsaturated soil of the core embankment dam.

An intelligent displacement back-analysis method for earth-rockfill dams
Computers and Geotechnics, 2007Abstract An intelligent method for the effective displacement back-analysis of earth-rockfill dams was proposed by combining artificial neural networks and evolutionary calculation. This method employs artificial neural networks, with optimal architecture trained by the evolutionary calculation and Vogl’s algorithm, instead of the time-consuming ...

The Analysis of Stress, Deformation and Arch Effect of the Lianghekou Earth-rockfill Dam
Indian Geotechnical Journal, 2015Deformation, stress and arch effect are problems of interest for high earth- rockfill dams. Deformations and stresses during construction, impoundment and operation stages of Lianghekou earth-rockfill dam were studied through numerical methods. The filling materials were modeled by using the Mohr- Coulomb and Burgers models.

Based on Cloud Model of Earth-Rockfill Dam Deformation Forecast
2012 Third Global Congress on Intelligent Systems, 2012The cloud model is a qualitative concept and its quantitative expression of uncertainty between the conversion models, and it can combine concept's fuzziness and randomness, to solve the problem of uncertainty. This article uses cloud models and cloud reasoning to predict the Earth-rock fill dam deformation, and initially solved the Earth-rock fill dam
