twin bore tunnel 中文意思是什麼
twin bore tunnel
解釋
雙孔隧道-
Through analyzing all kinds of construction methods of building metro station under shield driven method in many countries, this paper studies the construction technique ( method ) of building metro station under shield driven method, taking in guangzhou no. 3 metro line, and linhe xilu station as the actual object. according to station class, function and topography and geology, the station schemes of twin - bore tunnel ( island ), firstly, three parallel tunnels ( island ), tri - bore tunnel ( island or side ) and four parallel tunnels ( island or side ) are proposed. secondly, the shape and main parameters of station structure on two schemes are analyzed with load - structure mode, for different overburden depth of tunnel and lining thickness, etc. thirdly, the construction process is simulated in 2d fem.,
根據建站的規模、使用功能及站位地形地質條件，提出了兩連拱結構島式站臺車站、三條平行隧道島式站臺車站、三連拱結構島式和側式站臺車站以及四條平行隧道島式和側式站臺車站方案；採用荷載?結構模式，對四種方案的主體結構的形式和重要參數進行分析研究，分不同的埋深、襯砌結構厚度和拱形結構的拱跨比進行了多組數值計算；採用平面有限元方法對四種車站結構的開挖施作過程進行了模擬分析。 -
