考虑在管段墙体受底板的刚性和非刚性约束下,推导出管段墙体在预制过程中温度收缩应力的解析解答,并提出合理划分刚性和非刚性约束的浇筑时间间隔,为控制温度收缩应力和防止裂缝的产生提供了一种实用的计算方法。
Considering that the wall of the pipe is constrained by the rigidity and non-rigidity of the floor, the analytical solutions of the temperature shrinkage stress of the pipe wall in the process of prefabrication are deduced. The pouring time interval reasonably divided between rigid and non-rigid constraints is proposed. In order to control the temperature shrinkage stress And to prevent the generation of cracks provide a practical method of calculation.
