Water invasion bursten out during the railway - tunnel construction is usually the mainly problem in constructing or operating, also which brings surface water to exhaustion and pollutes environment or effects ecology, etc. the geleshan tunnel which crosses through guan - yin gorge anticline which trend is near south north, is located between tuanjie village and jingkou village of the shapingba zone, chongqing city, which is belongs to the inducting segment of yu - huai railway. the guan - yin gorge anticline appears to ridge and slot interlacing in land form, and is composed of clastic rock and carbonate rock from jurassic xintiangou group to triassic
歌樂山隧道位於渝懷線引入段重慶市沙坪壩區團結村至井口村之間，隧道穿越近南北向的觀音峽背斜，地貌上表現為脊、槽相間，觀音峽背斜由侏羅系新田溝組至三疊系下統碎屑巖和碳酸鹽巖組成，歌樂山頂大部分出露可溶巖地層，地表巖溶發育，有大量泉水和暗河出口，並修建有多個中小型水庫、大量池塘和水井。 -
Based on the investingation and some study methods of the stability on the goaf, the paper has the goaf of the first and second tunnels of wu long channel on coal mine railway leased line in da ning of shanxi province as an example, according to the engineering geological invesitigation and maping in the earth ' s surface, also combining the visit on the relate people, firstly has a geological judge on the space extend of the mostly ledges which have been picked ; then adopts the instrument of engineering surveying and checking ( for short sws ) which is relatively advanced inside and outside to test by surface wave the rockmass and solid near the middle line of the tunnel ( total forty meter ), and has a relatively exact judgment on the place that the goaf impossible reveal ; lastly passing the validate by drilling, it make clear that the results which tested by sws is reasonable and believable, based on finding out clearly the space extend of the goaf, the author makes a relatively systemic study on the stability of wall rock around the goaf
因此，查明采空區的具體位置，在此基礎上對場地進行工程適宜性評價，對整個工程建設具有重要的指導意義。本論文在總結前人對地下采空區勘察及有關穩定性研究方法的基礎上，以山西大寧煤礦鐵路專用線五龍溝1 ~ # 、 2 ~ #隧道采空區為研究實例，在詳細的地表工程地質調查和測繪的基礎上，結合通過對采空區有關人員的探訪，首先對主要開采礦層的空間展布進行地質判斷；然後採用國內外較為先進的工程勘探與檢測儀（簡稱「面波儀」 ） ，對1 ~ # 、 2 ~ #隧道中線兩側一定范圍內（共40米）進行了面波測試，對采空區的可能出露部位進行了較為準確的判斷；最後通過鉆探加以驗證，表明面波儀的測試結果是較為合理可信的。 -
