台灣地區由於板塊構造之關係，在東部及東北部地區時時有地震之發生，且由於『臺灣強地動觀測計畫』（TSMIP）於宜蘭地區設有多部強震儀，提供不少地震記錄，讓我們有機會針對宜蘭平原之場址效應進行有系統之研究。本子計畫將著重於研究宜蘭地區在大規模地震作用下之地動反應微分區圖。主要根據震源分區及其地震發生機率、地動衰減公式建立各震源區不同機率之地動分佈圖，如PGA，Sas，Sa1 及SI 等工程應用參數，其中SI 可供維生管線來應用。各震源可能造成之機率地動分佈圖，可提供宜蘭平原耐震設計、土地利用、區域發展規劃及大規模地震災害防治等之參考。 ; For the sake of the plate tectonics in Taiwan, many earthquakes will occur in the east and northeast Taiwan. Due to many strong motion accelerographs installed in the Ilan area and recorded many earthquakes by the TSMIP network. Let us have chance to focus on the Ilan plain to study the site effects systematically. The research will focus on the seismic microzonation of the Ilan plain. The ShakeMap on different probability of each source zone can be setup from the earthquake occur probability of each source zone and ground motion attenuation equations. For example, the PGA, Sas, Sa1, and SI. The ShakeMap on different probability of each source zone can apply to the reference of seismic design, land use, area development plane, and large scale earthquake hazard mitigation. ; 研究期間 9708 ~ 9807
