摘要
根据富阳连续刚构桥混凝土箱梁日照作用下的温度观测结果,研究箱梁沿断面高度的温度梯度分布规律.采用非线性回归的方法,提出了该桥混凝土箱梁的温度梯度模式.并对主梁立模标高提出了考虑温度影响的修正方法.
Based on observation results for concrete box girder of Fuyang continuous rigid frame bridge in the sunshine, distribution of temperature gradient along the height of cross section of box girder is discussed. The mode of temperature gradient of this bridge＇ s box girder is developed by the method of nonlinear regression. Furthermore, the real-time revision method is propose to elevation of the main beam considers the temperature influence.
