肋板橋 的英文怎麼說
中文拼音 [lèibǎnqiáo]
肋板橋
英文
ribbed slab bridge-
Steel decks, in other words, orthodox isomerism structures, are welded with various transverse and longitudinal reinforcing ribs. this results in the complexity of forces and deformatiort of the pavement layer above the deck
鋼橋面板焊接在各種橫向、縱向加勁肋上，橋面板為正交異性板結構，決定了其上的鋪裝層受力變形的復雜性。In virtue of finite element program, this paper calculates the model of rc - masonry combination arch bridge in the stages of construction and use in this paper. based on these data, it analyzes the structure behavior of the reinforced concrete arch ribs and the masonry arch ribs using methods of inner force and stress
本文藉助有限元程序對rc -石砌體組合拱橋的計算模型進行了施工階段和使用階段的計算，並採用應力疊加和內力疊加兩種方法對rc拱肋和石砌體拱板的受力特性進行分析。Grillage girder is always used for analysis the structures, such as dense ribbed slab, superstructure of bridge and grid - mat foundation. in this paper, a mechanical model for grillage girder by elastic supporting is proposed, and used for analysis the track structure for the first
交叉梁系一般用於求解密肋式屋面板、橋樑上部結構和格式基礎等結構，本文提出一種彈性支承交叉梁系模型，並首次用其求解軌道結構。The seperated pair of main ribs section was made up by bridge panel and girder, because its construction is convenient, used widely in the prestressing force concrete cable - stay bridge of large span
回答：分離式雙主肋截面是由橋面板與邊主梁組合而成，由於其施工方便，在大跨度預應力混凝土斜拉橋中得到廣泛應用。Reasons : firstly, sectional dimension is so little that torsional stiffness of single - beam is n ' t enough. secondly, protective layer thickness is too thin to protect concrete reinforced bar and reduce durability. lastly, each main beam is joined by cross girder and the more rigid of cross girder the more entirety of bridge
橋梁局部損壞較嚴重，主要原因是主梁截面尺寸過小、肋板過于薄弱，造成單梁抗扭剛度不足；保護層厚度不夠導致鋼筋外露引起銹蝕，降低了橋梁的耐久性；各主梁採用橫隔梁連接成整體，橫隔梁的剛度越大，橋梁的整體性越好，但調查結果顯示，實際情況中並不能達到理想的整體剛度。Because the intervals of two side girders are relatively large in the structure of the floor, it is not even and some and out of shape that its bridge of panels must be produced at the same time horizontally and crookedly and vertically except deforming wholly, level analyse can receive the satisfied result already at this moment, is it is it accord with floor structure real work state, girder of cable - stay bridge just to analyse with whole out of shape relevant non - linear space of function while being out of shape while being above - mentioned to consider only, but about this research rarely seen to report bridge worker is it understand their receive strength characteristic in an all - round way to need badly publicly
由於肋板結構中兩個邊主梁的間距較大，其橋面板除整體受力變形外必然同時產生橫向彎曲和縱向不均勻局部變形，此時平面分析已不能得到滿意的結果，只有考慮上述變形與整體變形相關作用的非線性空間分析才符合肋板結構主梁斜拉橋的實際工作狀況，但有關這方面的研究鮮見公開報道，橋梁工作者急需全面了解其受力特性。Therefore, it might be very essential to study the cable stayed bridge of the super breadth composite beam. additionally, the main problems of the study are as follows : 5 、 the distributing for stress of lengthways and transverse in transect ; 6 、 discussing the change of stress of lengthways and transverse, while the breadth of bridge is changing ; 7 、 in the cable stayed bridge of the super breadth composite beam, the lengthways reinforce rib and rigidity crossbeam exert influence on stress of bridge board ; 8 、 while tower and beam are concretion, main tower affects bridge board
鑒于目前關於此類橋型研究成果不多，就此作了下列若干問題的研究： 1 、超寬疊合梁斜拉橋橫斷面上縱向應力分佈和橫向應力分佈特點的研究； 2 、對超寬疊合梁斜拉橋隨著橋寬變化時，上述兩種應力分佈變化規律進行探討； 3 、在超寬疊合梁斜拉橋中，縱向加勁肋對橋面板受力的影響；橫梁尤其是剛性橫梁在橋面板受力中所起的作用； 4 、塔梁固結時，主塔對橋面板的作用。Based on the achievements done by others and the feature of superstructures, we establish the segment models under the different loads for the fem calculating of the deck and make it for the final conclusion that the distribution of the stresses in the deck of this main girder are uniform
本文結合已有的研究成果以及金馬大橋橋面系的結構特點，通過建立主梁的有限元節段模型，並分工況計算橋面板的正應力分佈情況。計算結果表明，肋板式斜拉橋主梁的橋面板正應力分佈是比較均勻的。分享友人
