  1. 地下管線過斷層之大變形行為及數值分析 題目： 題 林祖榕博士，國家地震工程研究中心 講者： 時地： 民國101,03,14 土木館五樓 • 三、過斷層自來水管線變形行為之參數分析 • -土壤和管線的互制 • Soil spring element models • Brick and contact element models • 數值結果 • Different fault motion • Different buried depths • Different soil properties • Case study 一、前言 • 集集大地震 • 東日本311大地震JSCE調查 • 二、過斷層自來水管線變形行為之 • 研究 • 解析公式 • Newmark理論 • Kennday理論 • 實驗方式 • 縮尺寸實驗 • 數值模擬 • 管體模擬 • 土壤管線互制模擬 四、結論 • 解析斷層運動對於過斷層之地下管線的結構安全會有嚴重威脅 • 地下管線受震後的主要破壞機制是取決於地層變形和地震波的傳遞 • 埋地管線的廣義的全域可用量元素，大變形用殼元素 • 數值模擬顯示斷層運動，埋設條件會影響管線整體反應 土層變為與地下管線損壞示意圖 感謝 林祖榕博士 精彩的演講
