由於台北盆地之特殊地質構造，當地震波穿越鬆軟之地層時，易受盆地內的場址特性影響形成震波放大現象造成各種地震災害，例如1999 年集集地震以及2002 年331 地震 。近年來台北盆地地震觀測系統以及地質資料調查日益齊備完整，提供地震研究非常優良的場址及相關資料。本研究將針對台北盆地現有之地震觀測資料做一系列地動特性分析，及土壤非線性效應研究，供強地動預估進一步研究；整合並建構台北盆地三維數值模型，提供數值計算預估強地動效應，探討二維三維震波傳遞現象。研究目標主要有(1)數值模擬方法優缺探討(2)藉由場址效應的研究，提供地震災防之參考(3)完成測試場址初步研究，推廣台北盆地為國際強地動預估測試場，藉由國際多方研究快速提升台北盆地在地震災害防治的技術。 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. 研究期間：9908 ~ 10007
