4 . by measuring the stress and the line deformation of control box section , i can assure the mode of temperature fields in long - span pc continuous box girder bridges and its effect on stress and the line deformation at certain time 4 、通过测量出的箱梁控制截面的应力和线形数据变化，确定某一时刻温度场模式对大跨度pc连续箱梁t构的应力和挠度的影响。
1 . according to the examples of engineering practice , we can build up temperature - calculating modes of box section and then calculate temperature fields of box section by measuring the boundary conditions and restricting conditions . 2 1 、结合工程实例，用有限元方法( ansys )建立箱梁截面的温度计算模型，由实测的边界条件和实际约束条件计算出箱梁截面的温度场。
Because of its simplicity of the critical moment and the good precision , the solutions based on gjelsvik theory are used in the elastic - plastic phase . the ultimate load carrying capacity of box section beams are calculated considering the effect of plasticity and residual stresses 其次，运用基于gielsvik约束扭转理论推导了箱形偏压杆的弹性弯扭屈曲荷载，同时给出了压弯杆在弹性弯扭屈曲的轴力和弯矩相关关系。
When the axis force p is much greater than the moment m , the out - of - plane column - instability mode is dominated . otherwise , the in - plane instability mode of the beam - column is dominated . at the end of this part , the practical formula of box section beam - columns is suggested which avoid the incorrect concept of 最后对数据进行分析、拟合，得到了实用的计算箱形柱压弯构件承载力的计算公式，并消除了规范中稳定系数罗_ b > 1 . 0的概念错误。
By measuring the temperature of temperature - feeling machine of pre depositing in the box sections , i can get the varying temperature data of different time in box sections , then make use of these temperature test datas , figure out the variety regulation of temperature distribution along the high direction in box section with the nerve network method , then i get temperature fields of box section along the high direction 3 、采用现场实测的方法，通过测量预埋在箱梁截面的温度传感器，得到不同时刻箱梁截面的温度变化数据，然后利用这些温度测试数据，用回归分析的方法拟合出沿梁高方向的温度分布规律，从而得到箱梁梁高方向的温度场。
