大跨径PC连续箱梁桥的温度场研究

以苏州斜港大桥为工程背景，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，然后利用这些数据用回归分析的方法拟合出了沿梁高方向的温度分布规律，从而得到箱梁沿梁高方向的温度场。

Study on temperature field of large span PC continuous box-girder bridge

Taking Suzhou Xiegang large Bridge as background,and based on the prediction of the temperature sensor that buried in box-girder section previously,the author gets temperature changing data of box-girder section in different time,then uses these data and fits the temperature distribution law along the direction of beam height based on the method of regression analysis,thus getting the temperature field along the direction of box-girder beam height.
