Resumen:

Stratigraphical variations within the same geotechnical environment may modify the seismic response of soft clay deposits. Two sites in Mexico City having typical stratigraphies are used to illustrate the influence of changing shear wave velocities on surface movements. Detailed profiles of shear wave velocities obtained from in situ measurements were modified at selected depths. The influence of these changes on seismic response is discussed in terms of their effects on spectral amplitudes and fundamental frequencies. The sensitivity of seismic response to changes in the shear wave velocity profiles is shown to depend on local stratigraphy. Some of the practical implications of the research are also discussed.
