    本文首先對國內外的研究現狀作了回顧和總結，然後主要針對土工織物加筋粉煤灰復合體的本構關系和計算理論進行研究，主要內容有： （ 1 ）將土工織物和周圍土體視為一種近似的彈性非線性橫觀各向同性體，研究它的應力應變關系，充分考慮它的各向異性，得到土工織物加筋粉煤灰復合體的本構模型，然後通過大量室內試驗進行分析驗證； （ 2 ）引入有關滲流理論，即柯茲尼-卡爾曼（ kozeny - carman ）經驗公式，將滲透系數引進到土體本構關系中。
  2. With the different loading ratio of parallel to axis and normal to axis direction, damage defects will occur bulking problem. by varying the degree of material anisotropy relative to the loading axis such as poisson ' s ratio and shear modulus, crack growth bulking strain value parallel to or normal to the loading axis is different. the parameters controlling the growth or arrest of the delamination damage are identified as the geometry and the depth of defects and radius of cylindrical etc. at last, it was investigated that the delamination damage is often induced by the tip of matrix damage under higher stress

    研究結果表明:殼體筒段受軸向拉伸和內壓載荷作用時，軸向和環向載荷的比率不同，母層和子層可能發生拉伸屈曲，也可能發生收縮屈曲，或者同時發生拉伸和壓縮屈曲;母層與子層各向異性存在差異，即泊松比與剪切模量不匹配時，將使子層板的邊界上承受壓縮和剪切作用，當分層達到臨界狀態則發生屈曲，當母層與子層的各向異性差異越大，則發生分層屈曲的可能性越大;分層損傷的屈曲應變值與子層自身的彈性模量、分層子層的形狀、厚度以及圓柱半徑等因素有關。
  3. Three different aspects of anisotropic deformation including lateral strain, relative proportional relation of lateral strain and strain in load direction, and train increment induced by unit stress increment in load direction will be delicately analyzed. the stress strain relationship in different principal stress load direction can be reflected in the anisotropy of tangent elastic ratio or strain increment in load direction induced by unit stress increment in load direction

    側向變形可以從側向應變、側向應變與加荷向應變之間的相對比例關系或側膨脹系數以及加荷向單位應力增量所引起的側向應變增量三個不同方面深入細致地分析研究；不同主應力加荷向的應力應變關系各向異性可以反映在切線彈模以及加荷向單位應力增量引起的加荷向應變增量的差異中。
  4. In the case of general anisotropy it is coupled with the ordinary plane strain problem.

    在一般各向異性情況下，它與普通手面應變問題綜合在一起了。
  5. This paper puts to use a tensile test from the plastic deformation theory, and has deduced the mathematical formulas on determing criterion in the various conditions such as the sotropy and anisotropy materials, plane stress, plane strain, space stress and strain

    文章採用拉伸試驗，根據塑性變形理論，推出了各向同性和各向異性材料在平面應力應變、空間應力應變等多種條件下的判斷準則的數學表達式。
  6. The research of soil anisotropic deformation characteristic in this paper is mainly to study the anisotropy of lateral deformation and the anisotropy of principal stress and principal strain relationship in different load direction

    本文土體各向異性變形性狀的研究主要為了研究側向變形以及不同主應力加荷向的主應力主應變關系的不同變化規律。
