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。 -
On the basis of the analysis of the test data, the additional force linearly increased with variation of water pressure in the aquifer, and increased with the increase of the depth and with the content of coarse soil particle in the overburden layer
試驗結果表明：豎直附加力隨含水層降壓量的增大而線性增加，隨深度增大而增大，隨土層中粗顆粒含量增多而增大。 -
The site overburden layer with the structure of different foundation soil strata and different rigidity of soil layer transforms structure of frequency of ground micro - tremor with different degree
土層結構不同、土層剛度（值）不同，覆蓋土層對地脈動源頻率結構的改造程度也不一。 -
Fourth, there exists some corresponding relationships between spectral structure characters of ground micro - tremor and shear wave velocity of site soil layers. the outcomes of these two kinds of tests can be conferred each other. fifth, the correlations between predominant period of ground micro - tremor and thickness, and value of shear wave velocity of overburden layer are established
第五，建立場地土覆蓋層厚度、剪切波速與地脈動卓越周期之間的相關關系，有助於通過勘測場地土覆蓋層厚度的結果估算場地地脈動的卓越周期，以及揭示場地土剪切波速與地脈動卓越周期的內在相關規律。 -
To estimate of ultimate bearing capacity from the cohesion and unit weight of soil and embedded depth ( overburden ), the kinematical approach of limit analysis based on the three - dimensional mechanism was used
文中利用極限分析中的機動法，構建了一個臨近基坑矩形淺基礎的三維機動許可破壞模式，按照地基承載力的傳統表達方式，分別給出了單獨考慮土的粘聚力、基礎埋深（超載）和土的自重影響的承載力系數。
