宽跨比 meaning in English
width-span ratio
Examples
- As is well known , the effective width depends on several factors , such as the cross - section width , the height of web , the spacing of span and so on . we can conclude that width / span ratio ( overhang width / span and central width / span ) is the governing factor of the effective width
影响箱形截面梁上翼缘有效宽度的因素很多,如上翼缘宽度、梁高、跨度以及结构体系等,通过大量计算表明宽跨比[翼缘部分宽度、箱室部分宽度与跨度的比值]是有效宽度的控制影响因素。 - The cfst x - type arches improve the lateral stability by sloping the arc ribs , so it is ofen used in the designs of cfst arch bridge with small ratio of the width to the span . tongwamen bridge is a half - through cfst arch bridge , its span is 238m , and the width of its roadway is 10m , so the truss ribs in - plane is sloped into x - shapc to improve its lateral stability . as the cfst x - type arches with longest span all over the country presently , the design of tongwamen bridge can be used for reference of adopting cfst x - type arches in the design of arch bridges with small ratio of the width to the span
钢管混凝土x型肋拱桥是一种利用拱肋侧倾来提高其横向整体稳定性的桥型，在宽跨比较小的钢管混凝土拱桥设计中应用较多。浙江铜瓦门大桥是一座中承式钢管混凝土无铰拱桥，跨径238m ，桥宽10m ，拱肋为平面桁架形式，所以采用了x型拱肋以提高其横向稳定性。作为国内目前跨径最大的钢管混凝土提篮拱桥，该桥的建成对我国今后长大跨径小宽跨比钢管混凝土拱桥采用提篮拱具有借鉴意义。 - Structural internal forces and deformation caused by seismic load are bigger than that caused by automotive load . seismic load controls the designing of large span and small " width - to - span " ratio of large span cfst arch bridge . the seismic resistance is bigger than that with considering combination of various directions , so seismic load combination of various directions should been taken into account during design of large span cfst arch bridge
地震荷载所引起的内力和变形均大于车辆荷载引起的内力变形，对大跨、宽跨比小的钢管混凝土拱桥来说，应以地震荷载控制内力和变形设计，考虑多方向地震荷载的组合后，所得的地震力更大，说明在计算地震力时，应该考虑多方向地震荷载的组合。 - At last , on the basis of the linear finite element model , the effect of different factors such as the stiffness of the arch rib , the arrangement form and the arrangement position of the lateral brace , the sloping angle of arch ribs , ratio of the width to the span , the form of the hangers , the stiffness of bridge decks , cables etc is discussed
最后,本文还通过有限元模型的分析,就拱肋自身刚度、横撑的布置形式和布置位置、拱肋内倾角、宽跨比、吊杆形式、桥面刚度、斜拉索等方面对该桥的整体稳定性的影响展开讨论和研究。 - The transverse stiffness limitation index ? the permissible ultimate width / span ratio b / l of the continuous steel truss girder of railway bridge is analyzed in accordance with the analytic theories of random vibration of train ? bridge time - variation system and the required derailment coefficients and comfort of drivers and passengers in train running through the bridge . the limitation index in question may be referred to in the design of the continuous steel truss girders of railway bridges
基于列车-桥梁时变系统随机振动分析理论，按照桥上列车脱轨安全系数和司机、旅客舒适度的要求，对铁路连续钢桁梁桥横向刚度限值-桥梁容许极限宽跨比b / l进行了分析，对铁路连续钢桁梁桥的设计具有一定的参考作用。
