有限元仿真分析是桥梁计算的有效手段和施工的依据,本文以MIDAS/Civil软件建立连续梁拱的有限元模型,分析主梁的应力值和位移值,并通过MIDAS/Civil软件自带的施工阶段联合截面分析灌注混凝土前后拱肋的应力值,并得到钢管和管内混凝土各自的应力值。
有限元倣真分析是橋樑計算的有效手段和施工的依據,本文以MIDAS/Civil軟件建立連續樑拱的有限元模型,分析主樑的應力值和位移值,併通過MIDAS/Civil軟件自帶的施工階段聯閤截麵分析灌註混凝土前後拱肋的應力值,併得到鋼管和管內混凝土各自的應力值。

The finite element simulation analysis is the effective method of the bridge’ s caculating and the basis of the con-struction.This paper use the MIDAS/Civil to establish the continuous composite arch’ s finite element model, analyse the beam’ s stress and displacement, use the construcion stage combinate section to analyse the arch rib’ s stress before and af-ter affusing the concrete,and to get the steel pipe and the inside concrete’ s stress.
