A NEW APPROACH FOR EVALUATION OF SEISMIC SLOPE PERFORMANCE
The evaluation of seismic slope performance during earthquakes is important, because the failure of slope (such as an earth dam, natural slope, or constructed earth embankment) can result in significant financial losses and human. It is important, therefore, to be able to forecast such displacements induced by earthquake. However, the traditional forecasting methods, such as empirical formulae,...
متن کاملPredicting Seismic Slope Displacements of Embankment Dams Using Fuzzy Systems
Iran, as a leading country in the dam construction industry, is located in one of the earthquake-prone regions of the world. Dams are important sources of hydroelectric power. Failure of these structures causes catastrophic damage. Therefore, evaluating the behavior of dams under seismic loading is an important issue. The present study focuses on the prediction of the slope displacements of emb...
متن کاملSeismic Coefficients for Pseudostatic Slope Analysis
Pseudostatic analysis is one of the simplest approaches used in earthquake engineering to analyze the seismic response of soil embankments and slopes. However, the choice of seismic coefficients used in the analysis can be arbitrary and generally lacks rationale. To investigate this, a parametric study was performed on a soil embankment of varied geometric characteristics and soil properties su...
متن کاملStudy and Application of Wavelet - based Denoising Method of Seismic Effect Signals of Colluvium Accumulation Slope
Stability analysis of ground motion topography effect is one of the important topics in geotechnical and earthquake engineering. In order to solve the major problems in seismic effect signals of colluvium accumulation slope in different target positions: weak echo signal and large dynamic range, we proposed an improved wavelet denoising analysis method. Through denoising experiments, we calcula...
متن کاملA Proposed Modeling Method in Finite Element Slope Stability Analysis
Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...
