| 摘 要： | 以大深坑II号大桥为例,建立桥梁结构计算模型。按我国公路桥梁设计规范、英国BS5400规范和新西兰规范确定三种计算模式,采用同济大学开发的《桥梁博士2.9版》平面杆系有限元分析程序对高墩连续刚构桥的温度效应进行计算分析、对比研究和探讨,提出了我国设计规范的应力计算结果小,是偏于不安全的。这为今后连续刚构桥的温度效应分析提供了另一种思路。

| Abstract: | Dalian Communication Planning, Survey & Design Institute, Dalian 116000)abstract:Taking Dashenkeng No 2 Bridge as an example, the bridge structural calculation model is set up in 3 calculation modes. Based on the calculation, analysis, comparison and discussion on temperature effect of continuous rigid frame bridge with finite element analysis program of plane bar system of Bridge Doctor 2.9 Edition, the point of view that the stress calculation results of design specifications of our country are rather too small to ensure the security has been proposed, providing another thought for temperature effect analysis of continuous rigid frame bridge. |
