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，从而获得有关截面的最大与最小应力。

Abstract：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 clement 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.

Key words： high-speed railway oblique arch bridge the end joint of arch part stress 8-joint isoparametric element
