9號煤半煤巖巷道錨桿錨索支護設計淺析This text handles a tunnel for draining off water in huangjiawangarbage ground, in yichangcities is for the example, intro - ducedthe support techniqueofthe anchored bar, thesprayed concrete associated withthereinforcement matwhich is used in theengineeringconstruction, and pass to monitor, express the support technique can develop to the maximum bearing, and become the passive support becomean active support, so the the support technique guarantees the stabilizationof the tunnel and the normal proceeding of theconstruction with theengineering
摘要以宜昌市黃家灣垃圾處理場排洪洞為例，介紹了錨噴網支護技術在淺埋軟弱圍巖隧洞施工中的應用，並通過監測，表明錨噴網支護能最大限度地發揮圍巖的自承能力、變被動支護為主動支護，從而保證隧洞圍巖的穩定和工程施工正常進行。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。The simple analyse to rational support methods of soft rock tunnel
軟巖巷道合理支護方式淺析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。Comments on soft rock support mode
軟巖巷道支護形式淺析The theory of floor heave in soft rock roadway
常村煤礦軟巖支護淺析Special attention should be paid to the flat tunnel with outsized span at shallow depth. apart from some common surveys, it is quite necessary to survey initial support stress, which is conducive to directly and accurately understanding changes of stress in surrounding rock and can provide helpful guidelines for governing tunnel construction in an importantly practical way
施工中必須進行監控量測，淺埋特大跨隧道施工除需進行常規項目量測外，必須進行初期支護應力量測，這樣可準確、直觀了解圍巖應力變化情況，對指導隧道施工、預防險情有著非常重要的現實意義。分享友人
