Estimating site amplification effects using shallow seismic data

SEG Technical Program Expanded Abstracts 1991, 1991
Shallow Pand SH-wave seismic reflection and refraction data from two sites in the Paducah, Kentucky, area have been used to develop soil column velocity structures in order to estimate site amplification effects resulting from an earthquake. Although the seismic data were of variable quality, numerous reflected and refracted events have been identified

Numerical simulation of seismic site amplification effects

2013
The concept of substructure deletion proposed for the analysis of a rigid embedded foundation was adapted for the analysis of site amplification effects in alluvial valleys. A major modification was made for the present application such that the boundary integration equation method was used for both the finite size interior problem and semi-infinite ...

Site Effect Analysis around the Seismically Induced Ananevo Rockslide, Kyrgyzstan

Bulletin of the Seismological Society of America, 2002
In 1911, the surface-wave magnitude 8.2 Kemin earthquake hit northeastern Tien Shan (Kyrgyzstan), close to the cities of Bishkek and Almaty, the capitals of Kyrgyzstan and Kazakhstan, respectively. Several hundreds of people were killed by the earthquake, some by indirect effects such as landslides and mudflows.

Evaluation of seismic site factors in the Mississippi Embayment. II. Probabilistic seismic hazard analysis with nonlinear site effects

Soil Dynamics and Earthquake Engineering, 2005
Abstract An integrated probabilistic seismic hazard analysis procedure that incorporates nonlinear site effects, PSHA-NL, is developed and used to characterize the influence of thick deposits of the upper Mississippi Embayment (ME) on seismic site coefficients.

Probabilistic Seismic Hazard Analysis Considering Nonlinear Site Effect

Bulletin of the Seismological Society of America, 2000
A modified method is proposed for the probabilistic seismic hazard analysis considering nonlinear site effect. A case study is presented to show the hazard curves that consider the nonlinearity of the soil layers at Gilroy #2. Source parameters and an earthquake occurrence model are assigned to the Caleveras fault, which is assumed the dominant seismic

Effects of Adjacent Ground Treatment on Site Seismic Response

Applied Mechanics and Materials, 2011
The effect of adjacent soil improvement on ground motion is studied using finite element method, when seismic wave is introduced from the single layer on bedrock. The influence of ground motion on soil reinforcement is analyzed; the impacts of the reinforcement zone width, depth, elastic modulus, and the soil improvement interval on response of the ...

Probabilistic seismic hazard analysis considering site-specific soil effects

Soil Dynamics and Earthquake Engineering, 2018
Abstract This study presents a framework to perform Probabilistic Seismic Hazard Analysis (PSHA) for soil sites, which yields accurate soil UHS and associated seismic hazard curves. The variabilities of soil parameters, the nonlinear responses of soils, and the vector-valued site responses analysis comprehensively integrate into the PSHA for soil ...

Seasonally Frozen Soil Effects on the Seismic Site Response

Journal of Cold Regions Engineering, 2011
Several large-magnitude earthquakes, including the Prince William Sound earthquake of March 1964 and the Denali earthquake of November 2002, occurred in the state of Alaska and caused considerable damages to its transportation system, including damage to several highway bridges and related infrastructure.
