  1. The result shows that the plasticity index and the compression coefficient of the northern inshore saline soil reduce with the increase of the salt content, and the shear strength attains a limit value with the increase of the salt content

    結果表明，北方濱海地區鹽漬土的塑性指標、壓縮系數隨含鹽量的增加而降低，抗剪強度隨含鹽量增加出現一含鹽量界限值。
  2. In the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages

    本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性，通過採用不同方法穩定該類土作底基層材料的力學性能研究，從技術、經濟角度綜合評價，得到滿足規范抗壓強度指標要求的水泥石灰穩定方案。通過對原材料、試驗配合比設計、施工、等方面進行優化，從而顯著減輕了基層的早期及長期縮裂程度，從而提高了路面的耐久性。
  3. The study shows that besides boundary conditions, the factors influencing the nonlinear consolidation behavior of soils are the compression index cc, the permeability index ck, the level and the rate of loading, and the thickness of soil, etc. in nonlinear consolidation, especially for layered soils, the average consolidation degree defined by settlement, us is greater than the one defined by effective stress, up, i. e., the rate of the development of settlement is greater than that of the dissipation of excess pore water pressure

    研究表明，除邊界條件外，影響軟土地基一維非線性固結性狀的主要因素是壓縮指數c _ c 、滲透指數c _ k 、荷載大小與加荷速率、土層厚度等。對于非線性固結，特別是成層地基，按沉降定義的平均固結度u _ s大於按有效應力定義的平均固結度u _ p ，即沉降發展速率要快于超靜孔壓消散的速率。
  4. The sedimentation compression lines of natural clays, intrinsic compression lines of reconstituted clays and oedometer compression curves can be normalized by a void index, then the difference of the structural clays and reconstituted clays as well as the gradual damage course of soil structure are showed apparently

    用孔隙指數來歸一化天然粘土的沉積壓縮曲線、重塑土的壓縮曲線和固結儀壓縮曲線，可以很清晰地揭示出結構性土與重塑土的內在差別、固結儀試驗中土體結構性的漸進破壞過程。
  5. Based on the new model, the influences caused by soil structure, apparent preconsolidation pressure, the re - compression index, the coefficient of secondary compression, the magnitude of loading, the coefficient of permeability, the rate of loading, the thickness of clay, the self - weight, the layered property etc, in the process consolidation of soil with structure, are analyzed in detail. the difference between the present model and yin & graham model was also given

    基於本文新建模型，分析論述土結構性、表觀前期固結壓力、再壓縮系數、次固結系數、荷載增量大小、滲透系數、加荷速率、固結層厚度、自重應力隨深度變化和土體成層性等對土固結的影響，比較本文模型與yin & graham模型的異同，闡述土結構性和流變性對軟土固結壓縮行為的影響。
