摘要
为实现对曲线钢箱梁桥顶推施工过程力学性能的探究,本文开展了对其相关研究。在明确项目工程基本概况的基础上,构建了曲线钢箱梁桥有限元模型。在研究过程中,建立曲线钢箱梁桥的空间有限元模型,对其在不同工况下的支座反力、挠度、扭转、内力与应力等进行数值仿真。并通过试验和数值模拟的对比,得出了不同工作状态下的受力和变形规律,从而验证了有限元方法的有效性。
In order to realize the research on the mechanical properties of curved steel box girder bridge in the process of incremental launching construction,this paper carried out relevant research on it.On the basis of clarifying the basic situation of the project,the finite element model of curved steel box girder bridge is constructed.In the process of research,the spatial finite element model of curved steel box girder bridge is established,and its support reaction,deflection,torsion,internal force and stress under different working conditions are numerically simulated.And by comparing experiments and numerical simulations,the stress and deformation patterns under different working states were obtained,thereby verifying the effectiveness of the finite element method.
