1) mining excavation of middle tunnel
暗挖中洞法
1.
The method of mining excavation of middle tunnel, with enormous constructing difficulties and great safety risks, was firstly applied in No.
目前国内地铁车站完全采用暗挖法施做并已投入使用的仅有北京地铁西单站、天安门西站、东单站和王府井站，主要是采用洞柱法、桩柱法和“双眼睛法”施工，而暗挖中洞法施工技术在国内双层地铁车站中还是首次在北京地铁五号线采用，施工难道大、安全风险大。
2) shield driven CRD method
浅埋暗挖中洞法
1.
Abstract: Based on the characteristics of the shield driven CRD method and taking the construction of Tiantan East-station of Beijing No.
针对浅埋暗挖中洞法的施工特点,结合北京地铁五号线天坛东门站工程,利用3D-σ有限元计算程序对其施工过程进行三维数值模拟,通过计算结果数据的整理与分析,总结了浅埋暗挖中洞法施工引起的地表沉降规律,得出中洞开挖、临时支撑拆除和二次衬砌施工是中洞法施工中对地层扰动较大工序的结论,并对今后类似施工提出了建议。
3) deep excavation of flat group cavities
平顶群洞暗挖法
4) open excavation changing into hidden hole
明挖改暗洞
