摘要

Site correction map derived from the slope of the topography is often well correlated with other independently-derived, regional-scale site-condition maps, but the latter maps vary in quality and continuity, and subsequently, also in their ability to match observed Vs³⁰ measurements contained therein （Wald et al, 2007）. This method has good application in＇the USA, as well as in Taiwan, Italy, and Australia. This paper elaborates on the theory and the method of generating shear-wave velocity maps and site correction amplification based on topographic slope, and studies the application in the 2008 Wenchuan M_S8.0 earthquake.
