大体积混凝土结构裂缝及其防治

ANALYSIS OF MASS CONCRETE STRUCTURAL CRACK AND PRECAUTION

介绍了大体积混凝土的含义及产生裂缝的原因，推导出在不同的条件下，大体积混凝土结构的温度应力和裂缝间距的计算公式。由此，讨论了在不同的温度条件下的应力状态和温度裂缝的分类，并提出了防治大体积混凝土结构裂缝出现的有效措施。

The conception of mass concrete and the influences on developing cracks were described. The formula of the temperature stress and the length of crack spacing was infered under the different conditions,and the states of stress under different temperature conditions as well as the category of temperature cracks were discussed. Some effective measures were proposed to prevent mass concrete structure from occurring cracks.
