" listen, hermine ; i consider myself as brave as most men, but when i drew from my breast the little key of the staircase, which i had found in my coat - that little key we both used to cherish so much, which you wished to have fastened to a golden ring - when i opened the door, and saw the pale moon shedding a long stream of white light on the spiral staircase like a spectre, i leaned against the wall, and nearly shrieked
我認為自己的勇氣並不比一般人差，我從上衣口袋裡摸出那把開樓梯門的小鑰匙。我們以前是怎麼珍視那把小鑰匙，您還曾希望把它拴在一隻金戒指上呢。當我打開那扇門，看到蒼白的月光泄到那座象鬼怪似的螺旋形樓梯上的時候，我一下子靠到了墻上，幾乎失聲大叫起來。 -
“ it is vital that women are measured and fitted so that their sports bra holds the breast tissue close to the chest wall to minimise bouncing, " she says
她說： 「重要的是應該給婦女們量體裁衣，這樣她們的運動胸衣才能讓乳房組織緊貼胸脯，從而減小跳動幅度。 」 -
The retaining wall reclining on the slight slope built on soft foundation is usually used in protecting the shore of river, the contradiction between the lack of impartiality in stress of the base and the small stress allowed by the foundation as well as the lack of stabilization of the breast wall is a hard nut to crack in the engineering. in the paper, a tenon - base is added under the base of the retaining wall, on the study of the choice of the parameters and formulas used in calculation and the research of theory used in calculation, method used to deal with the load, etc, the writer gives a way to crack the nut mentioned above paragraphs and presents a qualitative and quantitative analysis about them, such as the equivalent inner friction - angle ( d ) and the passive press of the clay ( ep ), etc. in the end of the paper, using modern optimization method, a design of the retaining wall reclining on the slight slope built on soft foundation is done, the result is economical, and accords with the fact
軟基上的仰斜式擋土墻在水利工程河道護岸中經常遇到，仰斜式擋土墻基底偏心應力較大和軟基土地基容許承載力偏小的矛盾以及擋土墻抗滑穩定不足是工程中難以解決的難題。本文在對仰斜式擋土墻設計中有關計算參數的選擇、公式的選用應該注意的問題進行了研究，對河道護岸軟基礎上的仰斜式擋土墻採用凸榫基礎處理的方法，就其計算理論、設計驗算中各荷載的具體處理方法進行了較為細致的研究，提出了解決軟基礎上的水工仰斜式擋土墻難以解決的難題的方法，並對有水情況下粘土等效內摩擦角_ d 、凸榫被動土壓力e _ p等在計算中的取值提出了定性和定量的分析。最後利用現代優化方法對軟基礎上的水工仰斜式擋土墻進行了結構優化設計，得出了符合實際的結果，與其它重力式擋土墻形式進行比較，取得了明顯的經濟效益。 -
Introduced by prestressed pier in the gate of spillway in xiao xia hydroelectric power station, the text reasonably established 3 - d finite elements mechanic model by the advanced finite elements popular in the world which can expediently impose tension of anchor funicular at its place. it also considered possible diversified combination of loading, and indicated that the effect of its prestressed action is fruitful compared with its conventional counterpart by study of mechanic calculation in comparison. as a result, it vastly improved burdening state of pier. by analysis of 3 - d finite element method, it also gained the stress result indifferent boundary conditions such as breast wall joint support and fixed support, and the displacement result in diversified loading combination. those results gained the instructive and reference value in design of prestressed pier
本文結合黃河小峽水電站泄洪閘預應力閘墩這一工程實踐，採用國際上已成熟的有限元方法，合理地建立了預應力閘墩的三維有限元模型，該模型可方便地按預應力錨索的點位施加錨索預張拉力，考慮了可能發生的多種荷載工況組合，並與無預應力閘墩結構進行了對比分析研究，指出其預應力效果是明顯的，可以大大改善閘墩結構的受力狀態，通過三維有限元分析，還得到了胸墻簡支、固端不同情況下的應力成果和各荷載下的位移成果，這些成果的取得對預應力閘墩的設計具有一定的指導和參考價值。 -
