  5. This thesis used along caldwell ' s direct calculation method of the ultimate strength of ship hull girders, considered the double bottom and upperwing tank to ship ultimate strength contribution, first defined the stress distribution of the whole section of the ship girders. that is : in the sagging condition, deck and side shell of nearby deck remain the ultimate bucking strength, double bottom remain the yield stress. and the other parts keep elasticity

    本文沿用caldwell等人直接計算船體極限強度的思想，考慮雙層底和頂邊水艙對船體極限強度的貢獻，首先將船體梁整體破壞時剖面應力分佈確定為：在中垂狀態下，甲板及甲板附近的舷側均屈曲，雙層底區域則均屈服，其他部分保持彈性狀態；在中拱狀態下，雙層底及之間的底舷側均屈曲，甲板及頂邊水艙區域均屈服，其他部分則保持彈性狀態。
  6. When there is original stage support only, the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress, correspondingly, the load ratio of initial stage support gets smaller. when the initial stage support and the second support act each other, the load ratio of surrounding rock is more than fifty percent, and it has little change with the increasing of crust stress. the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration, so do the sidewalls and the foot of a wall of the surrounding rock

    通過屈曲理論分析結果對比表明，彈性屈曲和突變失穩分析的結果比非線性屈曲分析的結果要大得多，非線性分析由於考慮了材料非線性和幾何非線性，因而結果與實際接近實際；當只有初期支護時，隨著地應力的增加，圍巖的荷載分擔率增大，相應地，初期支護的荷載分擔率就減小了；當有初期支護和二次襯砌共同作用時，圍巖的荷載分擔率在50以上，這一分擔率隨地應力的增加其變化不大；支護和巖體的整體分析表明，襯砌底拱及拱腳處應力集中嚴重，隧道巖體側墻及墻角圍巖的應力集中也較大。
  7. The arch : arms by the side and bend up both knees, then raise the buttocks ; to exercise the muscles in the thigh, buttocks and back

    拱橋;屈曲雙腿，提起臀部，放下鍛?大腿，臀部及背部肌肉，注意:由於拱橋運動量比較大，因此做完拱橋后，要休息一下，才做其他運動
  8. In summarizes the predecessor to the segmental arch surface and outside in flexure critical load computational method foundation, with the principle of the minimum potential energy, an analytical solution for the lateral critical bucking load of cable stayed arch bridge is studied

    在總結前人對圓弧拱的面內，面外屈曲臨界荷載計算方法的基礎上，利用能量法，推導了斜拉拱橋的側傾臨界荷載計算公式。
  9. Focuses are then put on the flexural torsional buckling analysis of mono - symmetry i - section arches. closed form solutions are obtained for arches subjected to uniformly distributed radial load and to equal and opposite end moments. effects of different laying positions and of asymmetry of cross - section on buckling loads are included

    在這個基礎上，對單軸對稱工字形截面拱在均勻受壓和均勻彎曲條件下的屈曲問題進行研究，給出臨界荷載的理論解答；分析了工字形截面不同放置形式和截面不對稱性對拱臨界荷載的影響，並與已有的理論進行比較。
