Webtopographic amplification factor. A ratio, calculated solely from topographic (terrain elevation) data, of the diurnal temperature amplitude or range in a valley to that at the same altitude over the adjacent plain. The diurnal amplitude is larger (or "amplified") over the valley than over the plain because the volume of air is less in the ... 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 …
On the role of topographic amplification in seismic slope instabilities ...
WebApr 21, 2024 · To quantify the topographic amplification effect, an amplification factor (R-PHA) is defined as the ratio of the peak horizontal acceleration (PHA) measured at a monitoring point to that measured at AT1; hence, R-PHA>1.0 indicates amplification, R-PHA = 1.0 indicates non-amplification, and R-PHA<1.0 indicates de-amplification. ... WebOct 26, 2024 · In order to analyze the impact of seismic waves on the venue earthquake, based on the display finite element method, the viscoelastic artificial boundary is used to analyze the variation of the ground motion amplification coefficient and the Fourier spectrum of the raised terrain under different incident angles with SV wave oblique … running apps on background

WebApr 15, 2024 · The possible effect of topographic amplification on rockfall triggering was investigated by comparing the distribution of rockfall source areas to the relief energy. In Fig. 8, cumulative per cent distribution is plotted versus RE r for the steep rock faces (dashed line) and rockfall source areas (solid line). The diagram shows a quasi-uniform ... WebJun 1, 1997 · The analysis of the site shows that although topographic amplification does in fact nearly double the amplitude of the motion in some cases, this amplification is offset by reduced site amplification and by wave splitting at material interfaces. Thus, the actual peak acceleration occurring at the crest of the slope changes little with incident ... WebAug 27, 2024 · In this research, topographic amplification is defined as the peak ground acceleration (PGA) for the crest to toe of the slope.
