Abstract：Based on the strong motion accelerations recorded by the topographical effect observation array in Xishan park, Zigong city from the mainshock of Wenchuan earthquake, 2008, the site effects of the ridge in the observation array site are studied through Horizontal-to-Vertical Spectral Ratio (HVSR) method, and the reliability of results is discussed. The strong motion accelerations of the observation array site are also simulated by the two-dimensional site model and analysis method, which are based on the explicit finite element-finite deference method and local transmitting boundary. This study indicates that the results of the numerical simulation and the observation data are strong consistent, and the simple two-dimensional site model is suitable for simulating the topographical effects on ground motions.
