摘要
沪宁线提篮拱桥是我国设计研究的第一座高速铁路大跨度预应力混凝土系杆拱桥。该桥拱脚的端横梁与相邻的拱座、拱肋、箱梁、支座承台的连接构造复杂。本文介绍应用 Super SAP软件的 8结点等参单元 ,对拱脚进行空间分析 。
The long span oblique arch bridge on Hu Ning high speed railway was designed and researched for the first time as the prestressed concrete tied arch bridge inside our country The link construction for the end cross beam of the arch bridge with the arch support, arch rib, box beam and supporting structure were complex. By 8 joint isoparametric element spatial analysis of Super SAP software, this paper expounds the results of the maximum stress and minimum stress relating to the sections of the end arch.
