  1. Generally, the skew bridge ' s calculation theories can be divided into three types : the category 1 is the plank theories method, such as the finite difference method, the finite element method and the finite strip method, etc ; the category 2 is the beam theories, such as the grid beam theories, the general grid theories, the rigid cross - beam method, the elastically - supported continuous beam method and the bar system analytical method, etc ; the category 3 is the practical method, such as the g - m revising method, the grid - beam simple method and ghali form coefficient method, etc

    目前關于斜梁橋的計算理論和方法概括起來，大致可以分為三類：第一類為板理論方法，如有限差分法、變分法、有限單元法、有限條法等；第二類為梁理論法，如格構梁理論、一般格構理論、剛性橫梁法、彈性支承連續法、桿件結構的分析方法；第三類為實用計演算法，荷載橫向分佈的計算方法如g ? m修正法、格構梁的簡易法、 ghali表格系數法等。
  2. Abstract : non - plank construction method of bottom - supported tied arch bridge makes possible of uninterrupt or short time in terrupt of navigation, having very high social and economic benefits

    文摘:下承式系桿拱橋無支架施工可以做到通航河流的不斷航或少斷航，具有很大的社會、經濟效益。
  3. This paper presents a study of the requirements of tied arch bridge constitution and construction from the perspective of design in relation to the specific requirements of non - plank construction

    本文針對無支架施工的具體要求，對系桿拱橋的構造要求及施工措施進行設計研究。
  4. The design realm in the province of jilin, use more software is the bridge doctor system, bridge master, system of asbest, procedure of qjx and province highway of jilins survey to design the hospital to by oneself develop of the t beam plank beam painting procedure, the cover beam calculation painting procedure, a pillar calculation procedure, the upper part procedure compute a procedure mostly, even some procedures can paint, but the province painting of basic and dissatisfied foot jilin of born diagram paper style, the diagram paper the modification quantity compare greatly, the procedure that the lower part procedure adopts to by oneself

    在吉林省內設計領域，使用較多的軟體是橋梁博士系統、橋梁大師、 asbest系統、 qjx程序及吉林省公路勘測設計院自行研發的t梁板梁繪圖程序，蓋梁計算繪圖程序，樁柱計算程序，上部程序多是計算型程序，即使有些程序能夠繪圖，但生成圖紙基本不滿足吉林省繪圖風格，圖紙修改量較大，下部程序多採用自行編制的程序，但大多數程序是dos系統的程序，使用不方便，同時與現行規范多有不符。
  5. 1. after a series of comprehensive testing and structure analysis to various bridges on the guangshe, huning, jinqin, shenshan, jingguang. ln our opinion, the key problems of the railroad bridge are as follows : ( 1 ) bridge construction is not well at the request of the railroad train speed - lift, primarily because of low dynamic property of the horizontal frame ; ( 2 ) the bad liability of the bridges structure, concrete beam ' s horizontal plank coupling form ; the low capacity of some of the bridges

    在對廣深、滬寧、京秦、沈山、京廣干線上不同橋梁結構進行的一系列綜合試驗的結果分析后認為，我國鐵路橋梁目前存在的主要問題為：橋梁結構不適應列車提速的要求，主要反映為結構橫向的動力性能較差；橋梁結構的耐久性問題；混凝土梁的橫隔板聯結方式；部分橋梁承載能力不足。
  6. Across it was a narrow foot - bridge ; but now the autumn flood had washed the handrail away, leaving the bare plank only, which, lying a few inches above the speeding current, formed a giddy pathway for even steady heads ; and tess had noticed from the window of the house in the daytime young men walking across upon it as a feat in balancing

    河上只有一座很窄的便橋但是現在河水已經把橋上的欄桿沖走了，只留下光禿禿的橋板，橋面離湍急的河水只有幾英寸，即使頭腦清醒的人走在這座橋上，也不免。要感到頭昏眼花苔絲在白天曾經從窗戶里看見，有一個年輕人從橋上走過去，就好像在表演走鋼絲的技巧。
