本文对超厚、超长钢筋混凝土建筑结构裂缝的基本概念和成因作了概要的叙述,介绍了控制温度裂缝的计算方法,提出了混凝土最高温升值的经验计算公式,同时对控制温度裂缝的施工技术措施和设计构造作了较为详细的论述,可供从事土建工程的大体积混凝土施工和设计工作者参考。
This paper gives a brief description of the basic concepts and causes of cracks in super-thick and super-long reinforced concrete structures. The calculation methods for controlling temperature cracks are introduced. The empirical calculation formulas for the maximum temperature rise of concrete are proposed. At the same time, the construction of temperature cracks is controlled. Technical measures and design structures are discussed in more detail and can be used as reference for large-volume concrete construction and design workers engaged in civil engineering.
