Study on Estimating Failure Probability of Earth-Rock Dams
Advanced Materials Research, 2012Dam safety based on risk analysis methodologies demands risk quantification of the earth-rock dam project, and estimation on the failure probability of earth-rock dams is a major concern in the dam safety management. Due to numerous uncertainties, structures of the reservoir are involved leading to risks that may finally cause dam failure.

Comparative study on slope stability analysis methods of earth-rock DAMS
Proceedings of the 8th International Conference on Informatics, Environment, Energy and Applications, 2019Combined with a soil-rock dam project, simplified bishop method, Swedish bar method and finite element strength reduction method are respectively adopted to analyze the influence of different working conditions and material selection. The limit equilibrium method USES nonlinear strength index to calculate the sliding arc.

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

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.

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.

Fully Coupled Dynamic Analysis of Earth and Rock-Filled Dam
Applied Mechanics and Materials, 2011The coupled 3D Dynamic Mechanical/Fluid is performed for the Nuozhadu earth and rock-filled dam by FLAC3D, but literature on the fully coupled of fluid-solid under earthquake is not too much. This paper gives a good example of applying FLAC3D to do the fully coupled simulation, and after a system in mechanical and fluid is got, the dynamic simulation ...

Three-dimensional seepage in the cores of rock-and-earth-fill dams
Hydrotechnical Construction, 19941. Consideration of the three-dimensional character of seepage flow in the region of shore abutments in rock-and-earth-fill dams exerts a major influence on the basic seepage parameters required for the design of the core profile, the gradation of soils in reciprocal filters of transitional layers, etc. 2. The three-dimensional character
