独塔大跨钢箱梁斜拉桥主塔承台温控计算研究

Study of Temperature Control Calculation on the Primary Tower Bearing of Slant-drawn Bridge of One Tower Large Span Steel Beam

利用朱伯芳院士提出的冷却水管等效法理论,采用三维有限元计算软件对广州珠江黄埔大桥北汊斜拉桥主塔承台大体积混凝土温度应力等进行了分析,确保了承台混凝土不出现温度裂纹。

Using the model theory of cooling water pipe advanced by Academician Zhu Lifang,this paper analyses the temperature stress of bulky concrete in primary tower bearing of Beihan slant-drawn bridge of Huangpu Great Bridge on Zhujiang River in Guangzhou by three-dimension unit calculating software,ensuring that temperature crackle won＇t appear in the bearing concrete.
