摘要
连续刚构桥的温度效应不容忽视,在T构阶段,温度变形影响立模标高的确定,能否对T构阶段进行温度效应的仿真计算与分析对桥梁建设提供参考在桥梁建设中有着重要意义,文中对某连续刚构箱梁桥T构阶段,通过大型应用软件ANSYS计算了温度应力及温度变形,从结构建模、加载、求解到后处理,说明了ANSYS在连续刚构箱梁桥温度效应计算中的应用,仿真分析和计算表明,对连续刚构桥T构阶段温度效应仿真计算与分析可行。
Temperature effect of continuous rigid frame bridge can not be ignored, in the T construction stage, thermal deformation influences how to choose the elevation of the template, it is of great important significance whether can the simulation calculation and analysis of thermal effect of continuous rigid frame bridge in T construction stage give some advice on the bridge construction or not. This paper calculates the thermal stress and deformation of a certain continuous box girder bridge in T construction Simulation analysis and calculation show that the simulation calculation and analysis of thermal effect of continuous rigid frame bridge in T construction stage is practical.
