  • Abstract Both the previous studies and measured earthquake
    acceleration recordshave indicated the focusing of wave
    energy due to the local irregularity ofground can generate large
    motion amplification in limited zones. This effect is of
    significance in the assessment of seismic risk. In this study,
    the eff-fect of local irregularity on the seismic moti-on is
    investigated using a non-linear effective stress finite element
    procedure which can also simulate thechange of water table
    during earthquakes.  The soilnonlinearity is accounted for
    using the cap model and the pore pressure model based on the cap
    model isalso adopted. The lateral infinite extent of soil
    stratum is modeled using theviscous boundary derived consi-
    dering the soil asa porous medium. The seismic responses at the
    surface of an alluvial basin underlain by rock are then stud-
    ied.From the analyses,it can be observed that (1). the steeper
    the rock slope is, the larger the responses at the surface are
    ;(2).as compared with the re-sults of elastic analysis, the
    nonlinear soil behavior will help reducing the surface
    acceleration responses but will increase the displacement
    responses; the similar observations can also be made for the
    soil stratum with lique-fiable soil;(3) the surface motions are
    less affected by the initial depth ofwater table.
