摘要
以３１６国道福建闽清石潭溪大桥施工受力为分析对象，进行了索梁混合结构稳定的有限元分析并编制了程序。应用ＳＡＰ９３程序研究了管内混凝土浇筑过程中的应力和稳定问题，提出的加载程序应用于实际施工中，应力测试与电算结果基本吻合。
The constructional forces of Shitanxi bridge which is part of the 316 national highway in Minqing Fujian province are analyzed. The stability of cable member mixed structure is analyzed using the finite element method and a corresponding program is also made. The SAP93 structural analytic program is used to study the stress and stabilty of concrete inside the steel tube during the pouring procedure. The loading procedure suggested in the paper can also be applied into the practical construction work, and the result of stress testing during the construction agrees well with those achieved by computer analysis.
