超长混凝土结构温度效应分析与工程实践

Analysis of temperature variation on super-long concrete structures and engineering practice

在总结超长混凝土结构设计中考虑温度应力、混凝土收缩和徐变的常用方法后,从结构布置、材料选择等方面论述了减小温差收缩效应的设计措施。最后列举了工程实例,该工程已竣工近一年,经历一个温度变化周期,效果良好。本文中所述设计方法及措施对同类型的超长混凝土结构设计有一定的参考作用。

The specific method is presented in the design of super-long concrete structures, which takes the temperature stress, concrete shrinkage and creep into account. The structural arrangement, material selection and other aspects of measures to reduce shrinkage of temperature effect of the design are then discussed in detail. A practical engineering is presented at last, which has been finished nearly a year. The result is good through the use of a temperature cycle. The method described in the text has some reference to the design of super-long concrete structures with the same type.
