摘　　要：为了研究处于自然环境条件下的高墩大跨混凝土结构,在日照温度荷载作用下产生的温度应力和变形,并由此引起的桥墩裂缝,以洺水大桥105.09m的高墩为工程背景,基于ANSYS的二次开发功能,编制了专用程序用来分析空心墩结构的温度场和温差效应,对不同壁厚矩形双肢薄壁墩的温度场及温差效应进行了仿真分析。In order to study the concrete structure with high pier and long span placed on the natural environment, in the sunlight temperature load effect, causing pier cracks and seriously engineering accdients, the Mingshui bridge＇s 105.09 meter high pier as engineering background, based on the secondary development function of ANSYS, the hollow pier structure temperature effect and temperature field analysis of special procedures,having a simulation analysis of temperature field and the effect of temperature difference with different wall thickness.
