摘要

The paper outlines a procedure for seismic microzonation for environmental planning and management, in the broadest sense, to assist in the planning, construction and management of projects. The procedure involves the following steps: (1) evaluation of the regional geology and typical subsurface soil profiles in the area or region being studied; (2) estimation of the dynamic stiffness and damping characteristics of the subsurface soils; (3) estimation of design histories of bedrock acceleration versus time; (4) carrying out seismic response analyses of typical soil profiles subjected to these earthquake histories; (5) assessment of site liquefaction potential; (6) assessment of seismic effects on stability of slopes and retaining structures; (7) calculation of structural response spectra and assessment of potential for structural damage; and (8) the appropriate portrayal of the results.
