The paper analyzes the reasons to this,mainly from temperature stress,and expounds technical measures including reducing temperature stress,configuring temperature reinforcement ,and etc.
大体积混凝土出现裂缝是一普通现象 ,本文主要从温度应力等方面分析了其成因 ,并从减小温度应力和配置温度钢筋等方面阐述了对其有害温度裂缝的宽度和深度进行控制的技术措施。
The numerical results show that the cracks are caused by cold wave by lack of temperature reinforcements in the structure.
计算结果表明,裂缝是由于结构未配置温度钢筋,由寒潮作用引起的。
With the simple model, some examples are shown to compare the provisions for minimum shrinkage and temperature reinforcement in GB 50010-2002 Code, ACI 318-02 Code and AS 3600-1988 Code.
利用该模型,通过算例比较中国GB50010-2002、美国ACI318-02、澳大利亚AS3600-1988三国规范关于混凝土板温度收缩钢筋的最小配筋率要求,并对此提出了设计建议。
