Research on Simulation Analysis of Arch Rib Concrete Grouting Sequence of V- type Rigid- frame Continuous Combined Beam Arch Bridge

V型刚构连续梁组合拱桥是充分将钢管混凝土拱桥和V型刚构桥的各自造型、美观、受力等优点融合一体的一种新型桥梁结构形式。不同的拱肋混凝土顶升灌注施工顺序,对主拱肋钢管应力和变形会产生不同的影响。通过V形刚构加拱组合结构拱肋混凝土采用上述两种顶升灌注施工顺序进行仿真模拟分析,主要目的是研究两种拱肋混凝土顶升灌注对V型刚构连续梁组合拱桥主拱肋应力和变形的影响。

V- type rigid- frame continuous combined beam arch bridge is a new form of bridge structure fully integrating the respective advantages of modeling, beauty, stress and etc. of the concrete filled steel tube arch bridge and V- type rigid frame bridge. The different arch rib concrete lifting grouting construction sequences will produce the different effects to the stress and deformation of the main arch rib steel pipe. The article introduces the simulation analysis of two lifting grouting construction sequences of arch rib concrete of V- type rigid- frame arch combined structure. The main objective is to study the effects of two arch rib concrete lifting grouting sequences on the stress and deformation of the main arch rib of the V- type rigid- frame continuous beam combined arch bridge.
