  2. 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。
  3. The collapsible loess is often met during the construction of the high - grade highway in the loess area, and the main failure is the uneven subsidence of the roadbed and the culvert, which affects the safe usage of the roadbed and the culvert, etc. directed against this, based on the chankou - lanzhou freeway construction, the paper analyzes the application of the composite ground formed by lime - soil pile under the bridge and designs the project, discusses the rules of the contact pressure, the stress ratio of the pile and the soil, compares the p - s curves of one pile, the composite ground formed by one pile and the composite ground formed by two piles based on the in - situ plate loading test, evaluates the bearing capacity of the composite ground of the project

    黃土地區的高等級公路建設中經常遇到濕陷性黃土問題，其病害類型主要是地基土受水浸濕后引起路基、橋臺、涵洞等的不均勻沉降，直接影響路基、構造物等的正常使用。針對此問題，本文依託甘肅讒口至蘭州柳溝河高速公路建設工程，對橋基灰土樁復合地基應用的可行性進行了深入分析，根據具體工程進行了合理的設計與計算，並配合現場靜載荷試驗及壓力盒實測數據，探討了基底應力分佈規律，樁土應力比，變形模量的變化關系，對比分析了單樁、單樁復合和雙樁復合的p ? s關系，對橋基灰土樁復合地基承載力進行了整體評價。
  4. In connection with impact compaction technology of soil & stone cushion of third airstrip of pudong airport, it selects such experiment research as constructive technology & quality control, puts forward such constructive control parameters as pressing subsidence ratio ( single subsidence ratio ), pressing times, pseudo thickness and so on

    摘要基於浦東機場三期跑道山皮石墊層採用沖擊壓實技術進行壓實的問題，選取試驗段進行了施工工藝及質量控制等試驗研究，提出了沖壓沉降率（分計沉降量） 、沖壓遍數、虛鋪厚度等施工控制參數。
  5. It was shown that salt expansion value of low liquid - limit clay was accumulated before the sixth freezing and thawing cycles, but the increment of salt expansion was reduced gradually with increasing cycles ; the salt expansion accumulation of low liquid - limit clay could be separated into three phases ; the deformation of clayey sand was mostly frost heave and subsidence under cycles, and collapsibility value of clayey sand was accumulated with increasing cycles ; the variation of salt expansion ratio and collapsibility ratio was a parabolic function of freezing and thawing cycles

    試驗結果表明：低液限粘土前五次凍融循環過程中鹽脹具有較好累加性，隨著凍融循環次數的增加，鹽脹量增長速度逐漸降低；含砂低液限粘土的鹽脹過程可以被分為三個階段；粘土質砂在凍融循環過程中的變形主要為凍脹和沉降變形，具有較好的溶陷累加性；低液限粘土、含砂低液限粘土的鹽脹率和粘土質砂的溶陷率與凍融周期之間的關系符合二次拋物線變化規律。
