| 摘 要： | 结合现场调研结果,根据有关混凝土内部应力方面的著述、资料,对混凝土裂缝产生的原因、现场混凝土温度的控制以及预防裂缝的措施等进行阐述。混凝土裂缝的产生除了自身特性、施工养护条件等原因外,施工温度对裂缝的产生也有明显的因果关系。施工时控制调节施工温度对于防止混凝土裂缝的出现具有积极意义。

| Abstract: | This paper expatiates on the reasons leading to cracks in concrete,the control of the concrete temperature and the construction process,and the measures to prevent the cracks,according to the field survey and the literature on the existing stress in concrete.It is found that the temperature has significant effects on the cracks in concrete except the characteristics of concrete and the maintenance conditions during the construction.Therefore,the control of the temperature is meaningful to preventing cracks. |
