  1. Considering the similitude law for shaking table test, we study the test results and obtain some conclusions which are a ) generally, the silty soil in test box liquefies and the liquefied time has relation with the amplitude of acceleration, b ) when the intensity is on and above eight degree, the silty soil deposit will be liquefied dramatically, c ) the relationship of the pore water pressure is relevant to the cycle loading which represents when the cycle loading ranges from little to great, the relationship is represent as a concave curve, or else as a protruding curve and tends to stability. ( 3 ) based on the triaxial compression test and the resonant column test, some studies are made such as a ) the duncan - chang parameters of constitutive model, b ) the dynamic shear modulus ratio and c ) the damping ratio of the site soil deposits. in order to deal with the test data, a computer program is compiled

    （ 2 ）利用小型振動臺進行了k _ 0固結狀態下粉土的振動液化模擬研究，通過分析正弦荷載作用下的試驗資料，驗證了粉土的孔隙水壓力增長模式的合理性；從微分方程推導了基於土體振動臺模型試驗的相似律，並從模型實體、孔壓時程曲線和相似律等方面做出了分析，得出了如下結論：在小型振動臺試驗中，模型箱中的粉土都發生了液化，液化的時刻和輸入加速度幅值有關，而對頻率的變化不太敏感；粉土在相當於8 9度地震烈度的加速度幅值作用下可能產生嚴重的液化；孔壓的增長曲線形狀與施加的荷載有關：當施加荷載為由小到大的形式時，曲線形狀為上凹的曲線；當施加荷載為等幅的正弦荷載或荷載幅值由大到小時，曲線形狀為上凸的曲線，且逐漸趨于穩定。
  2. The bridges will gradually wear down under the circumstances of the natural environment, such as the atmosphere erosion, the changes of the temperature and the humidity, and applied environment, such as the loading, the fatigue of the material and the structure

    橋梁長期在自然環境（大氣腐蝕、溫度、濕度變化）和使用環境（荷載作用與頻率的增加、材料與結構的疲勞）的作用下，會出現逐漸退化的趨勢。
  3. There is a slight drop of the fcpr when the specimen s thickness increases. however, the thickness of the specimen exerts a great influence on kth and fatigue life ( n ) : the thicker specimen is, the higher fatigue life ( n ) becomes, and the greater kth shows. under control of the same conditions, the fcpr of am50 is not so high as that of az91. there are some correlations between load ratio ( r ) and the fatigue surface : when load ratio becomes great, small flat surfaces increase while dimples decrease

    試樣厚度增大，穩態裂紋擴展速率略有減小。但是，試樣厚度影響試樣的疲勞壽命和門檻值：試樣越厚，疲勞壽命越長，門檻值越大；在試樣尺寸和加載條件相同的情況下， am50的疲勞裂紋擴展速率較az91小，疲勞壽命則比az91長。載荷比r影響試樣的斷口形貌：載荷比r越大，對應相同k值出的斷口小平面越多，韌窩越少。
  4. In the procedure, the column is first divided into a finite number of small segments in equal length. the deflection - curvature relation of each segment is determined using the finite - difference method. the final nonlinear algebraic equations are then obtained by means of the equilibrium condition for each segment

    運用這種方法，先將長柱離散成若干等長的柱段，利用差分方法求得各柱段截面上的撓度與曲率的關系，再根據各截面上外力與抵抗力的平衡條件，得到一組關于荷載與變形關系的非線性代數方程組；本文對該方程組採用載荷增量法進行迭代求解。
  5. For each curvature incremental step, a deformed curve in the correspondi ng state can be determined for the column. through the iteration for all incremental steps until the solution is convergent, the complete load - deformation relation can then be obtained

    對各曲率增量進行反復迭代，直至得到收斂解，就獲得了長柱從加載到破壞的全過程變形曲線及荷載-撓度曲線。
  6. Contracted with the calculations of dam in rigid foundation, the frequencies are lesson and periods of dam are lengthened because of elastic restraint of foundation. and under earthquake load, the maximum displacement of dam top is larger

    與剛性地基下壩體計算結果相比，由於地基的彈性約束作用，壩體的自振頻率降低，周期延長；且在地震荷載作用下，壩頂最大動位移增大。
