Dynamic Analysis for Earth Rock-Fill Dam Including Dam-Reservoir-Foundation Interaction
Earth and Space 2010, 2010In the traditional studies on earth-rockfill dam seismic response, earth-rockfill dam material is usually analyzed as single-phase medium, besides that, current investigation related to the dynamic study of earth-rockfill dam-reservoir-foundation problems are still limited. In this paper, the seismic response of earth-rockfill dam was analyzed by using

Simulation of seepage field of earth-rock dam in heavy rains
2011 International Conference on Consumer Electronics, Communications and Networks (CECNet), 2011A drastic change will happen on seepage field of earth-rock dam in heavy rains, which may cause seepage damage and instability. So it has important significance to correctly analyze the change rule of seepage field of earth-rock dam in heavy rains, and rationally evaluate the safety of earth-rock dam during rainstorm period.

Seepage in inclined antiseepage elements of earth-rock dams
Hydrotechnical Construction, 1992The presently existing methods or calculating seepage in inclined ASEs have a limited area of use and often give substantial deviations from the actual values. At the same time, no analytical relations are known for calculating Iex in the backwater zone of the LP.

Seismic Analysis of an Earth-Rock Dam on Thick Alluvial Deposit
Advanced Materials Research, 2012The nonlinear dynamic FEM was applied to analyze the dynamic response of a core-wall earth-rock dam on thick loess alluvial deposit. The dynamic responses of acceleration, dynamic displacement, permanent deformation and the liquefaction state of the dam were obtained.

Study on Seismic Permanent Deformation of Earth Rock Fill Dam
Applied Mechanics and Materials, 2011For the flaw of safety evaluation system using safety factor as control index, seismic permanent deformation is used to evaluate the safety of earth rock fill dam. In this study, the seismic deformation of Zipingpu dam after Wenchuan earthquake is measured and analysis. The deformation in the middle of the riverbed on the crest is the largest.

Hierarchic Genetic Algorithm for the Initial Omission Settlement of the Earth-Rock Dam
2007 International Conference on Machine Learning and Cybernetics, 2007The exterior and interior displacements of the earth-rock dam are the important characters which can reflect its operation state. And it also has pivotal function in evaluating the quality of the project and judging whether the crack of the dam appears. The initial omission settlement is a popular problem in the observation of the earth-rock distortion.

Breach mechanism and numerical simulation for seepage failure of earth-rock dams
Science China Technological Sciences, 2012In this study, a numerical model, which can capture the full process of the development of seepage passages, the collapse of dams and the failure due to overtopping, is proposed for earth-rock dams. The critical incipient velocity for the occurrence of seepage failure is derived by analyzing the forces acting on soil particles in the seepage passage ...
