摘要
采用有限元分析软件ANSYS对大型桥墩的温度场及温度应力进行数值仿真,进而详细分析环境气温对桥墩温度场及温度应力的影响,探求在温度突变情况下桥墩的开裂机理,总结类似的大型混凝土温度场和温度应力变化的一般规律,提出保护方案及建议。
In the article, numerical simulation will be used to analyze temperature field and temperature stress in big pier with ANSYS. Then, in order to seek the crackle mechanism of the big pier in case of environmental temperature changing suddenly, the impaction produced by en- vironmental temperature on big pier temperature field and temperature stress of the environmental temperature will be studied in detail. Sum- marize the universal law of temperature field and temperature stress changing in similar large-scale concrete, and propose the protection scheme and suggestion.
