    隨著海洋油氣開發的迅速發展,發現海上構築物的失穩與工程地基特性有著密切關系,而國內外幾大油氣開采區地基土中均有大量粉土分佈,本文的研究區? ?黃河水下三角州埕島海域也是如此。
  3. Based on comparison of several technical schemes, the method of sand bedding pre - elevating and step water - filling pre - compressing is adopted. so the dissertation is consist of two parts : ( 1 ) the applicability study for the method of sand bedding pre - elevating and step water - filling pre - compressing, including numerical analyses for the thickness of sand bedding, the consolidation, settlement and stability of foundation, drainage, possibility of foundation liquefaction under seismic loading, et al. ( 2 ) monitoring at construction stage and checking the effect of foundation treatment, including the measurements of the settlement velocity and non - uniform settlement of ring beam under the tank, pore pressures and horizontal displacements in foundation, the pressure distribution at the bottom of oil tank and the strength increase of soils

    通過多種技術方案比較,最終選擇了技術先進的砂墊層預抬高分級充水預壓法,論文工作主要由以下兩部分組成: ( 1 )砂墊層預抬高分級充水預壓法的適用性研究,其中包括砂墊層厚度、地基沉降與固結度、地基穩定性、降水、地震作用下砂土液化的可能性等方面的計算分析; ( 2 )施工監測與地基處理效果檢驗,其中包括油罐環梁基礎沉降速率與不均勻沉降程度、各分級充水加載階段地基超靜孔壓與深層水平位移、油罐底板壓力分佈及地基土強度增長等方面的實測與數據分析。
  4. Based on the results of these tests, strength model and pore water pressure model have been advanced and validated. in addition, not only have the liquefaction mechanism of the soils been analysed, but also the influence of the factors on the extent of liquefaction of the saturated soils have been discussed

    在總結前人工作的基礎上,結合本次試驗成果,分析了飽和土體的液化機理及其影響因素,主要討論了土性條件(包括試樣密度、顆粒特性、固結時間、超固結及其結構性)和初始有效固結壓力的影響。
  5. With the data recorded by computer, the author studies the experiment progress in detail, which includes the development of pore press, strain, strength of the sand, etc. connecting the development of these phenomena with the development of stress path, the author finds new mechanism which can explain the phenomena in the experiment. what is more, according to the dynamic test of the sand, there appears a steady state at the last phase of the development of strain and stress path, in which the strength of the sand is studied because it is an important parameter in evaluating the stability of sand against liquefaction. secondly, the dynamic constitutive relation was studied through the dynamic tri - axial test

    本文首先採用目前國內較先進的微機控制動三軸儀,利用其可以適時採集和儲存數據的優勢,對砂土的實驗過程進行了細致的分析,研究該過程中孔隙水壓力發展、軸向應變發展以及它們與應力路徑之間的關系,對飽和砂土的剪脹、剪縮和卸載體縮等多個方面進行了研究,探索了砂土的動力特性,分析了影響砂土抗剪強度的各種因素,這些因素既包括土本身的特性(土的密度、結構、級配、透水性以及初始狀態等) ,又包括動荷載的特徵(振動力幅值大小和振動頻率等) 。
