標題: | 岩石隧道受震行為及破壞模式之研究(1/2) | 作者: | 黃燦輝 | 公開日期: | 2004 | 出版社: | 臺北市:國立臺灣大學土木工程學系暨研究所 | 摘要: | 1999 年921 集集大地震後,台灣有多座岩石隧道遭受損壞,除洞口段受 損外,隧道襯砌亦產生了裂縫,然岩石隧道目前並無可靠量化之規範可供參 考使用。鑑於台灣地震發生頻繁,且隧道總長度已逾數百公里,岩石隧道之 耐震分析與設計課題之研究,甚為殷切。 本計畫為二年期研究計畫,第一年之工作內容包括:「國內外震後隧道 破壞案例蒐集」﹑「隧道受震時之破壞模式、力學機制與影響因素探討」﹑「土 壤隧道耐震分析設計之應用及適用範圍探討」﹑「岩石與土壤隧道耐震分析之 差異」﹑「隧道受震分析模式之建立與驗證」﹑「不同覆蓋深度隧道之受震行為 初步研究」﹑「隧道襯砌與岩盤互制對於隧道受震影響初步探討」等;本計畫第 二年之預期工作項目,除延續「不同覆蓋深度隧道之受震行為研究」及「隧道襯 砌與岩盤互制對於隧道受震影響探討外,另包括:「地質弱帶與隧道相對位 置,對於地震時隧道影響分析」﹑「隧道一次及二次支撐(襯砌)受震行為研究」﹑ 「地形效應(地表起伏之影響) 」 ﹑「含節理等值岩體之波傳特性」﹑「案例分析 與比較」﹑「岩石隧道耐震分析與設計建議」等。本報告為針對第一年(九十二 年八月~九十三年七月)提出之期中進度報告。 After the 921 Chi-Chi Earthquake, many tunnels in Taiwan suffered damages. Besides damages in the portal portion, the inner lining also suffered damages that occurred in the portion with higher overburden which usually gives no damages in accordance with past experiences. It has no seismic design and also has no seismic code to be abided by. Taiwan is an earthquake-prone country and many tunnels stretch a few hundred kilometers long. Therefore, the study on the earthquake resistant analyses and designs of rock tunnels has became increasing important. This projet is 2-year long.The work scope for the first year include the collection of local and overseas rock tunnel failure cases due to earthquakes, the analysis of the various factors causing the earthquake effects, rock tunnel failure mode during earthquake and its mechanisms, evaluation of the suitability and limitations of the use of soil tunnel seismic resistant design specifications to rock tunnel design, establishment of appropriate analysis model,preliminary analysis of tunnel’s behavior with different overburden during earthquake, preliminary analysis of influence of interaction between lining and surrounding rock on rock tunnel. Besides continuing analysis work of tunnel behavior with different overburden during earthquake and influence of interaction between lining and surrounding rock on rock tunnel, the work scope for the second year include influence of distance between weakness zone and tunnel ,study on behavior of primary and secondary lining during earthquake ,topographic effect ,characterestics of wave transmission for equivalent jointed rock mass,case studies and comparison with analysis results,suggestion for analysis and design for rock tunnel seismic resistant design. This report is submitted as mid–term report for the first year job(2003/8~2004/7). |
