Three-Dimensional scattering of plane harmonic SH, SV, and P waves in multilayered alluvial valleys

Asian Journal of Civil Engineering 01/2010; 11(5):605-626.


In this paper, three-dimensional amplification of plane harmonic SH, SV, and P waves in multilayered alluvial valleys is investigated by using a boundary element method in frequency domain. It is shown that in order to achieve real responses, the problem must be analyzed and modeled three-dimensionally. Also, for exact evaluation of surface ground motions in alluvial valleys all key parameters such as layering, material and geometrical characteristics of each layer, stimulation frequency, wave type, plus angle and azimuth of incidence must be taken into account altogether. The accuracy and efficiency of the proposed formulations for the computation of the surface displacement field amplification is verified by solving a number of problems.

    ABSTRACT: Earthquake-induced landslides are among themost destructive slopemovements, not only because of their size andmagnitude, but also because of the synergistic action with the earthquake the consequences are higher, due to the earthquake shaking and the landslide effect. Studies on landslides triggered by seismic activities are not as extensive as rainfall-induced landslides. In this study, a quantitative risk analysis approachwas used to calculate the risk for people exposed to the threat of earthquake-induced landslide in Emamzadeh Ali, north of Iran. Emamzadeh Ali was selected as it has already experienced some landslides and is located in a tectonically active region. A numerical model was used in this study to carry out the stability analysis of the slope, under both static and dynamic conditions. A quantitative probabilistic approach was developed for determining the frequency and magnitude of the process. In addition, the values of vulnerability for each building were calculated. The highest risks (individual risk to life and societal risk to life) are in the area of the stone mine on the head of the slope and close to the toppling activities north-east of the study area. © 2011 Elsevier B.V.
