Topographic amplification
WebOct 1, 2024 · The topographic effect on ground motion amplification significantly decreases with an increase of the distance to the crest and it tends to zero in the vicinity of the free-field boundary. The intensity of amplification and the distribution of the maximum amplification on the ground surface behind the slope crest changes significantly with ... WebJan 1, 2012 · To study the amplification effect of slopes due to topographic and geological condition of the slope material, a homogenous slope model and a slope model with alternating layers of tuff and shale were built using ABAQUS software (Fig. 6). The homogenous slope model was taken to be wholly composed of tuffaceous material while …

WebMay 17, 2024 · A tropical cyclone transports a large amount of sea water to land as water vapor. The water becomes a torrential downpour, and the rainwater temporarily staying on land depresses the solid earth as a load. WebNov 11, 2007 · In this paper, we evaluate the additive effects of topography, soil nonlinearity, and soil-structure interaction (SSI) along the crest of an idealized 40 m high cliff-type topographic feature with slope inclination 30 0, where excessive damage was observed during the Athens 1999 earthquake.The objective of this paper is to investigate the …
WebSep 20, 2024 · The topographic site effect plays a vital role in controlling the characteristics of earthquake ground motions. Due to its complexity, the factors affecting topographic amplification have not been fully identified. In this study, 100 ground motion simulations generated by double-couple point sources in the homogeneous linear elastic half-space … WebLastly, we couple the DRM with the PMLs to complete the seismic motion simulation engine. Using the developed toolchain, we then report results of parametric studies involving idealized topographic features, which show motion amplification that depends, as expected, on the relation between the topographic features' characteristics and the ...
WebThe seismic topographic effect is one of the debated research topics in seismology and earthquake engineering. This debate is due to the discrepancy between the observed amplification and the amplification underestimation in numerical simulations.
