The article is devoted to the dynamic problems of studying strain state earth dams under impacts. A method developed for solving wave determine stress-strain structures, in particular, dams. Based on use finite difference method, an algorithm and calculation formulas were that have second-order accuracy time coordinates. advantage implementation complex nonlinear deformation models, taking into...

Evaluation of the accuracy of the pseudostatic approach is governed by the accuracy with which the simple pseudostatic inertial forces represent the complex dynamic inertial forces that actually exist in an earthquake. In this study, the Upper San Fernando and Kitayama earth dams, which have been designed using the pseudostatic approach and damaged during the 1971 San Fernando and 1995 Kobe ear...

The article is devoted to studying the stress-strain state (SSS) and assessing strength of Gissarak, Sokh, Pachkamar earth dams in a plane statement under action body forces hydrostatic pressure. A mathematical model, algorithm, computer program for structures are developed using Lagrange variational equation. finite element method was used problem solution. adequacy model accuracy algorithm we...

For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....

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 China. The dynamic analysis is carried out by ...
