Abstract:	目前，常用的強地動衰減式，主要是以地表站的資料作為分析來源，用以評估地表建物所可能遭受的強地動值，做為地表建物耐震設計的參考。然而，重要的公共工程建設，例如核電廠等，主要建在岩盤站上，若以一般的地動衰減式做耐震設計評估，高估的數值將造成巨額的成本。若能提供基盤面的地動衰減式，或是淺層場址的地動放大值倍率，一方面可以更瞭解基盤站的地動特性，另一方面則可讓地表站的地動值評估更具彈性。本研究將利用中央氣象局新一代井下地震觀測網，估算地表和井下站的最大加速度以及速度振幅值的放大倍率，完成全台的放大倍率圖，並試圖找出放大倍率與速度值之間的關係式。 ;At present, the general used Ground Motion Prediction Equation (GMPE) in Taiwan is driven by the data of surface ground motion stations. This GMPE provides an expected ground motion value of building on the surface sediment and gives an reference for buildings codes. However, the important public infrastructure (e.g. nuclear power plant) is supposed to be built in a site of hard rock basement, the GMPE developed by surface data would overestimate the costs for the building codes. In this study, we are going to analyze the amplification factors of PGA and PGV for the sediments over the basement by using the next generation seismic network of CWB. The amplification maps for PGA and PGV, and the relation between the amplification factors and Vs value are going to be obtained. ;研究期間：10501 ~ 10512
