摘要
引入温度梯度函数,研究了钢筋混凝土空心薄壁墩温度梯度的分布规律。结合西南地区某大桥的实例,对混凝土桥梁温度场边界条件进行模拟,并进行有限元分析,将理论参数与实际值拟合对比,通过温度梯度函数指数参数的变化说明不同季节下薄壁墩壁厚及其方位对温度梯度分布规律的影响。
The temperature d istribution’s regular pattern of steel concrete thin-walled hollow pier is studied in this article linked with the temperature gradient function.With the example of a bridge and finite element analysis,temperature filed’s border condition of steel concrete bridge is simulated and theoretical values are compared with virtual values.Through the changes of temperature filed function’exponential parameter,the effects which the thickness of thin-walled hollow pier and its position angles cause to the regular pattern of the temperature distribution can be concluded.
