| dc.description.abstract | 本研究首先摘要回顧目前各種地下結構物受震分析方法，並檢討各種分析方法之優劣，再從中建議出修正強制變形法與動態歷時分析法，並詳細說明與探討其分析流程與相關數值細節，包括土壤組成模式的測試、水壓激發模式之開發、邊界條件、邊界距離、網格大小、界面元素、地震動之模擬等。再將之與本研究建議之簡化結構元素非線性模式相結合，使所建議之地下結構物受震分析法可完整考慮土壤與結構非線性互制行為。最後再進行一系列真實或假設隧道受震案例之比較分析，以探究各種隧道受震情況下之行為反應，並藉以驗証所建議地下結構物受震分析法之合理性。由分析結顯示，所建議之分析方法可完整地掌握隧道受震時的非線性行為反應，當運用在新三義隧道與日本大開隧道受震分析時，可合理地模擬出隧道塌陷破壞的行為。所評估的耐震能力亦與真實情況相近，顯示所建議之方法具有相當良好的實用性與合理性。就分析方法適用性而言，比較分析結果與隧道實際受震情況後，對於岩石隧道，所建議的修正強制變形法與動態歷時分析法均有良好的模擬效果。但是對於軟土隧道或是位在具液化潛能土層內的隧道則較適合採用動態歷時分析。

| dc.description.abstract | This research proposed modified cross section racking deformation (MCSRD) method and dynamic time history analysis to deal with the complicated problem of underground structure subject to seismic loading. The analysis procedures and several numerical key points of the proposed methods were discussed and studied in detail with several model examples. A simplified model for simulating nonlinear mechanic behavior of structure has been developed and combined into the two proposed methods for fully considering nonlinear interaction of tunnel and ground during analysis.
The proposed nonlinear approaches were examined by several real or assumed cases of underground structures subject seismic loading, and the nonlinear collapse behavior of Daikai subway station during 1995 Kobe earthquake and the spalling of second lining of new Sanyi railway tunnel during 1999 Chi-Chi earthquake were satisfyingly simulated. Based on the results, the second lining should be suitably reinforced in seismic area. Dynamic time history analysis is needed for the tunnel embedded in liquefiable soil and the shallow tunnel in soft soil where the inertial force of tunnel structure plays an important role.
