天花湖水庫築壩材料之靜、動態特性與未來土壩動態分析研究之探討

Abstract

苗栗地區在台灣地震史上，屬於地震活動極活躍之地區。天花湖水庫未來若需考量未來土壩之受地震影響下之動態行為，包括地震危害度、壩基岩盤與以及築壩材料夯實後之靜動態特性、動態分析如何進行均應加以掌握。本計劃擬探討天花湖水庫土壩之地震危害度、壩基岩盤與築壩材料夯實後之靜、動態剪力特性、及未來合理可行之動態分析策略與方法。The Tien-Hwa Lake Reservoir locates within a seismic-active region. The planning and design of the earth dam should take its dynamic behavior in a potential strong earthquake into account. Aspects including seismic risk, static/dynamic mechanical properties of geo-materials, and the strategy of dynamic analysis must be studied. This project aims to investigate these aspects for the Tien-Hwa Lake Reservoir.
