Soil amplification: some refinements

International Journal of Soil Dynamics and Earthquake Engineering, 1984
Abstract The most widely used techniques for the study of one-dimensional amplification of vertically propagating seismic waves involve solution of the dynamic equations in the frequency domain with linearly viscoelastic material properties. Material nonlinearities are approximately modeled by iterative use of linear solutions, adjusting values of ...

Soil Amplification Study for Kalyani Region, Kolkata

2021
The main objectives of the present paper are: (i) to identify the areas in Kalyani region, Kolkata, i.e. AIIMS Kolkata campus in which soil formations are prone to amplifying ground motions and (ii) to analytically evaluate amplification ratio using computer program for earthquake site response analysis.

Soil amplification of plane seismic waves

Physics of the Earth and Planetary Interiors, 1980
Abstract Amplitudes of surface particle velocities are calculated when time-harmonic seismic waves of uniform amplitude are incident upon an arbitrary stratified elastic soil layer from the underlying bedrock. Whereas previous workers have mainly treated normally incident S waves, we allow the waves to be of SV, P, or SH types and to have arbitrary ...

Subsoil geology and soil amplification in Mexico Valley

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1991
The Mexico Valley earthquake of 1985 was devastating and the extent of the damage is attributed to the very exceptional and extreme geological and topological conditions in the area. Mexico Valley is a 'bowl' of about 22 km in length and 1.5 km in depth. Figure 1 shows the Valley and the distribution of damage and the location of stations where records
