  1. The effect of overburden separation dynamic development under key stratum on grouting for bed separation space was analyzed, in order to deal with the problem that the current bed separation growing technology can not prevent the key stratum from breakage, put forward the isolated section - grouting technology for overburden bed separation space, integrated the virtue of growing for bed separation space and partial extraction, the bed separation grouting bodies, key stratum and isolated section pillars were made to constitute the load - carrying body all together, and to reach the purpose of reducing subsidence effectively, increase the coal seam extraction ratio, and accelerate the development of isolated section - growing technology for overburden bed separation space

    摘要分析了關鍵層下離層動態發育對離層充填的影響，針對目前離層區充填工藝不能阻止覆巖關鍵層初次破斷的問題，提出了「覆巖離層分區隔離注漿充填」技術，它綜合離層充填與條帶開采技術的優點，通過離層區充填置換或減小分區隔離煤柱寬度，使「離層區充填體關鍵層分區隔離煤柱」形成共同承載體，從而達到有效減緩地面沉降的目的，提高了煤層采出率，促進了覆巖離層充填減沉技術的發展。
  2. 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。
  3. The results show that ( 1 ) the unconsolidated confined aquifer plays a crucial role in load transfer because of its fluidity and replenishment in time, making the loads of overburden soil evenly transfer into the bedrock through the unconsolidated confined aquifer and the load keep constant during the excavation process ; ( 2 ) under the condition without unconsolidated confined aquifer, the load on the bedrock will be reduced sharply during the excavation

    研究結果表明：鬆散承壓含水層條件下，由於承壓水的流動性和補給作用，上覆表土層的載荷通過鬆散承壓含水層均勻地作用於下部基巖上，開挖過程中基巖頂界面上的載荷基本保持恆定，鬆散承壓含水層起到均勻傳遞載荷的作用；無鬆散承壓含水層時，作用在基巖頂界面上的表土層載荷隨煤層開挖而顯著降低。
  4. In this paper the friction piles are used in zipingpu multi - purpose dam construction project, the spillway in the side slope is covered with overburden, the horizontal area is from sp. 0 + 200m to sp. 0 + 280m, the elevation is about from el. 810m to el. 950m, there is hard and integral rock under the overburden, which provides enough anchor ability, and it ' s requirement to set the friction pile at the appropriate place ; in order to improve the slope stability that suitable excavation or weeding off the disadvantage load on the landslide are good measures, for the scarp it ' s better to reduce the slope

    摘要紫坪鋪水利樞紐工程溢洪道樁號0 + 200 ~ 0 + 280 、高程810 ~ 950m范圍的內側邊坡為覆蓋層邊坡，坡體下部有較為完整堅硬的巖石，具備提供足夠錨固力的條件，在適當的位置可以考慮設置抗滑樁，再通過適量的開挖提高邊坡穩定性，或將滑坡體上部不利於穩定的荷載挖除，對于陡坡的坡面可以將坡削緩，則效果會更好。
  5. Therefore, in the process of load transfer within the unconsolidated confined aquifer, the key strata of overburden rock are prone to have a compound breakage when the load on the upper interface of bedrock is great and the bedrock is very thin

    在鬆散承壓含水層的載荷傳遞作用下，作用在基巖頂界面的載荷較大，當基巖厚度較薄時，采場覆巖關鍵層易產生復合破斷。
