中文摘要 | 本文以數值方法分析長公路隧道內溫升現象受深層地下水活動之影響,本文應用 合理之工程數據與考量實際工程斷面,以有效率之數值模式,建立一簡易之分析工具,用以 評估隧道內溫升現象,並期能提供工程實際應用與研擬對策參考。由自行發展之半隱式計算 模式中, 使用貼壁格網系統及有限解析法,併合 Lagrangian 觀點,以 SOR 疊代方式推算 隧道附近區域地下水熱流場、混凝土襯砌防水層內外區域與隧道內部氣流溫度場。本文藉由 測試格網之數值實驗,以驗證結果之合理性。並由滲流參數之變化,而估算地下水活動對隧 道溫升現象之影響。 |
英文摘要 | This paper applied a numerical method to analyze the temperature rise inside an expressway tunnel. The temperature inside a tunnel rises under normal operation because of the excess of the generated heat to the design capacity of its ventilating system. By using the practical engineering data with efficient numerical schemes, the present study established a simple and useful tool to study the heat transfer in tunnel for real applications. The developed model was based on the semi-implicit method, in association with the boundaryfitting grid system, the finite-analytic method, and the Lagrangian-viewpoint analyses, to investigate the groundwater flow, and thermodynamic fields of concrete sidewall and ventilating air in a tunnel. The influences of the seepage flow on the tunnel's temperature were also discussed through examining the variety in hydraulic conductivity of groundwater motion. |
