在日照温度分布理论以及有限元分析方法的基础上,利用ANSYS的二次开发功能,编制了双肢矩形薄壁空心墩结构的温度场和温差效应分析的专用程序,并结合实例验证了仿真分析的准确性。同时以某高墩大跨连续刚构桥的双肢薄壁墩为研究对象,利用二次开发成果,对双肢矩形薄壁空心墩在日照温度荷载作用下的温度效应进行了分析,得出了双肢薄壁墩结构在悬臂状态与铰支状态两种不同的工况下,桥墩的温度应力与整体变形。结论可以为双肢薄壁墩的设计和施工提供参考。

This paper provides the prestressed concrete box girder continuous steel of MingShui bridge of XingFen High Way(80 m+3 × 150 m+80 m) as the engineering background, introduces sunshine temperature distribution theory and finite element analysis method of the double-limb thin pier. The ANSYS secondary devel-opment function, which is used to establish the analysis program for effects of temperature and temperature differ-ence for the double limb pier with rectangular thin-walled hollow, and verifies the accuracy of the simulation a-nalysis with examples. Using the ANSYS secondary development results, this paper analyses the temperature effects under the loads of sunshine temperature of the double limb pier with rectangular thin-walled hollow, and obtains the temperature stress and overall deformation of the pier in the different conditions-cantilever state and hinged status. This paper may provide reference for the ANSYS secondary development and the temperature con-trol of the double limbs of thin-walled pier.
