研究期間：10108~10207;Taipei located in a special sediment-filled basin structure the shock wave will amplify and cause damage due to the soft formation. For instance, the 1999 Chi-Chi earthquake and the 2002 March 31 earthquakes. Recently with the comprehensive data base of observed accelerograms and information on basin geometry, the Taipei basin represents one of the best sites in the world where basin and site effects for strong motion prediction, numerical modeling and earthquakes studied. This study intends to perform analysis of Taipei basin response and basic characteristic on earthquake ground motion and the soil nonlinear effects. The result will apply to the strong motion prediction study. Second is combined and produced the velocity model of Taipei basin for 2D and 3D numerical modeling. The main goals of the proposed research are : (1)comparision of the difference numerical modeling method (2)apply the site effects study results into seismic hazard prevention (3) incorporation of the results popularize Taipei basin to international strong motion prediction test site, in terms of international research develop the seismic hazard prevention technique of Taipei basin.
