中文拼音 [dūnduān]
墩端
英文
nose-
Two numerating methods are used in traditional structural design of gate chamber. first, considering the gate frusta to be fastened on the weir body, it is calculated as plane stress problem independently. then applying the results ( moment and vertical force ) on the bottom of gate frusta as concentrating load on the weir body, and the weir body is viewed as a elastic foundation beam or plate and unilateral stress analysis was performed
傳統閘室結構計算有兩種計算方法,其一是將閘墩視為固端于堰體上,單獨進行閘墩平面受力計算,再將閘墩下部的計算結果(彎矩和垂直力)作為集中荷載作用於堰體上,堰體作為彈性地基梁或板進行片面應力計算。The construction techniques of sinking well and explode in water are introduced. auto climbing form panel technique is applied in the construction of main tower
斜拉橋主橋墩設計為鋼筋混凝土圓端型沉井結構,其中詳細介紹了沉井下沉施工技術,同時介紹了水下松動控制爆破技術。The variable-depth girder is 4. 96m deep at the piers and 1. 83m deep at midspan and its extremities.
梁高是變化的,在橋墩處為4.96米,在跨中和端部為1.83米。The variable - depth girder is 4. 96m deep at the piers and 1. 83m deep at midspan and its extremities
梁高是變化的,在橋墩處為4 . 96米,在跨中和端部為1 . 83米。Ignoring the jerking of her chest muscles and holding her breath resolutely, she pushed away from the post and swam along the bridge shadow. the bridge was long, but it had to lead to shallow water. she kept going
顧不得胸肌的抽搐,拼全力憋住呼吸,她離橋墩那根支柱,沿著橋的影子游去。橋是很長,但總有淺水橋端。她不停地游。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。For the structure that the side - frusta is also used as retain wall, considering the side frusta fastened on the weir body, the plane stress is calculated at first. then the moments, horizontal shear force and vertical force on the bottom of the retain wall are applied as fixate, and stress distribution on the weir body are calculated piecewise
對于邊墩兼作擋上墻結構,通常是將邊墩視為固端于巖體上,先進行下端為固端的擋墻平面受力計算,再將擋墻下部的彎矩、水平剪力和垂直力作為集中外荷載進行堰體的應力計算,堰體也只能分段進行片面受力計算。This is especially a problem in extreme climates where water can get into the cracks between supports, freeze and expand and cause a huge amount of damage
特別是在極端氣溫中,水會滲進橋墩之間裂縫,冷凍擴大並造成巨大的傷害。 」分享友人
