摘要:
针对长联低墩连续刚构桥中边墩的受力特点,结合钢管混凝土结构的优势,提出采用钢管混凝土结构作为此类刚构桥的桥墩,并对其展开相应的研究.以渭河大桥八孔连续刚构桥为例,采用有限元软件Midas civil比较分析钢管混凝土桥墩和钢筋混凝土桥墩在结构内力分配、适应上部结构变形、材料用量方面的差异.结果表明:钢管混凝土桥墩比同等条件下钢筋混凝土桥墩的抗推刚度更小,更能适应上部结构的变形,结构受力更加均衡,材料用量更少,工程造价更低.通过比较两种桥墩在不同墩高情况下的墩顶最大水平位移值,指出了钢管混凝土桥墩的合理墩高适用范围.
Abstract:
In view of the mechanical characteristics of side pier in long span and low pier continuous rigidframe bridge,combined with the advantages of concrete flled steel tubular structure,we propose for the firsttime as pier of such rigid frame bridge,and carry out the corresponding research.Taking Weihe it bridge asan example which is an eight span continuous rigid frame bridge,by the finite element software Midas eivil,we comparatively analyzed the steel tube concrete piers and reinforced concrete piers in adapting to the upperstructural deformation,the internal force distribution,the amount of material. The results show that comparedwith the reinforced concrete piers under the same conditions,the steel tube concrete piers have smaller anti-push rigidity,better ability to adapt to the upper structural deformation,more balanced structure force,lessmaterial consumption,and lower project cost. By comparing the maximum horizontal displacement at pier topof two kinds of pier with different heights,we pointed out the reasonable application scope of the steel tubeconcrete piers.
