單拱單柱雙層淺埋暗挖地鐵車站二次襯砌優化施工技術 -
Concerning the construction of the shallow cover and the special shallow cover in the tunnel under the special geology conditions, the principle of " to stabilize the slopes with protecting arch ; to strengthen the earth with the pipe - shield support grouting ; to dig a hole shallowly ; to blast slightly ; to use strong supporting structure. " has been adopted to enter the tunnel safely ; in terms of the broken belt, the effective actions such as the pipe - shield support grouting, strengthening the surrounding rock in advance with advanced bolt and steel grids, and so on, are taken to pass the poor conditioned part smoothly
對于特殊地質中的淺理、特淺埋進洞的施工，堅持「護拱穩定邊仰坡，大管棚注漿加固土體，淺打眼、弱爆破、強支護」的原則，做到安全進洞；對于斷層破碎帶，則採取了管棚注漿，超前錨桿預先加固圍巖並結合鋼格柵支撐等有力措施，順利通過了不良地段。 -

淺埋偏壓連拱隧道中導洞坍方數值分析與處治 -
In this paper the different middle wall ' s mechanical behavior on different rock mass has been simulated by establishing the three - dimensional finite - element model of the shallow double - linked - arch tunnel, and the basic loading law of the middle wall is obtained, then the proper form of middle wall under different rock mass during constructing the shallow double - linked - arch tunnel is given, which offers foundation for the design of middle wall in double - linked - arch tunnel
通過建立雙連拱隧道的三維有限元模型，模擬了不同圍巖級別條件下淺埋雙連拱隧道不同中墻形式的力學行為，得出了中墻的基本受力規律，提出了不同圍巖級別條件下修建淺埋雙連拱隧道所採用的合理中墻形式，為雙連拱隧道的中墻設計提供依據。 -
Construction of flat tunnel of large span at extra - shallow depth must be conducted on the principle that advance grouting should be strictly performed before excavation and length of pull at one time should be short, together with reinforced support, immediate closing and constant monitoring and surveying. that preceding pilot tunnels, large - volume excavation divided into small ones, excavation of flank before that of center, upper before lower, arch before wall etc is a good method which could effectively reduce surface subsidence and its adverse effect on adjacent buildings, in addition, some other measures are also taken to lessen blast - induced vibration in the ground and surrounding structures. in a word, all means and steps mentioned above have already proved effective and practicable in practice
軟弱大跨超淺埋扁平隧道必須按「管超前，嚴注漿，多分部、短開挖、強支護、快封閉，勤量測」的施工原則進行施工，採用「眼鏡超前，化大為小，先側后中，先上後下，先拱后墻」的施工方法控制地表沉降和對周邊建築物的影響；採用「多分部，化大為小，短進尺，密布眼，弱裝藥，設減振槽」 ，控制爆破振動，經過實踐證明，這些方法都是行之有效的。 -
By adopting the calculating analysis method of elastic - plastic three - dimensional fem numeric simulation, this paper makes a simulation analysis on the structure stability of the shallow cover and unsymmetrically loaded parts in tongyoushan tunnel, mainly simulates the effects caused by different construction orders on surroundings and supporting structure stability, and it centers on the analysis on the weak part, the midwall in the lining of the connecting - arch tunnel
摘要採用彈塑性三維有限元數值模擬計算分析的方法，對桐油山隧道淺埋、偏壓地段結構穩定性進行了模擬分析，主要模擬了不同施工順序對圍巖及支護結構穩定性的影響，重點對連拱隧道整體襯砌中的薄弱環節中墻進行了分析。 -
Huangmeishan tunnel is the controlling project of maanshan - wuhu expressway, and also the 1st large span twin - arch tunnel constructed under the condition of shallow burying soft surrounding rocks in anhui province. the depth buried at the port of the tunnel is shallow, and it is covered with accumulated and disposal soil
黃梅山隧道是馬蕪（馬鞍山?蕪湖）高速公路控制工程，是安徽省在淺埋軟弱圍巖條件下修建的第一條大跨度雙連拱隧道。隧道洞口段埋深淺，且為坡積物和人工棄土覆蓋，圍巖鬆散，自承能力差。
