EARTH CORE ROCKFILL DAM: INTERACTION OF WATER AND SOIL
International Journal for Computational Civil and Structural EngineeringAccuracy of results of numerical modeling of the structure stress-strain state (SSS) depends on adequacy of design scheme. At elaboration of design scheme of an embankment dam the important aspect is selection of force loads from water. Water medium may

Inverse Parametric Analysis of Seismic Permanent Deformation for Earth‐Rockfill Dams Using Artificial Neural Networks [PDF]
Mathematical Problems in Engineering, 2012 This paper investigates the potential application of artificial neural networks in permanent deformation parameter identification for rockfill dams. Two kinds of neural network models, multilayer feedforward network (BP) and radial basis function (RBF) networks, are adopted to identify the parameters of seismic permanent deformation for Zipingpu Dam in

Probability Analysis Method of Seismic Response for Earth-Rockfill Dams [PDF]
AbstractSeismic response probabilistic analysis for earth-rock dams is a crucial step in performance-based seismic safety evaluation. It represents a significant transition from deterministic analysis to stochastic analysis. To conduct such an analysis, it's essential to thoroughly consider the uncertainties associated with the seismic response of ...

CONVERTER, 2021 Wide grading gravelly soil is an advantageous anti-seepage material in construction of high earth-rock dam. From the experience of earth-rockfill dam construction at home and abroad, it is more and more common to use wide grading gravelly soils such as moraine soil, weathered rock and gravel soil as anti-seepage material in construction of high earth ...
