| 摘 要： | 混凝土构件裂缝宽度的计算复杂、难度大,国内外学者都投入了大量的精力来研究其计算方法,多年来发展了很多计算理论。主要介绍国内除混凝土规范运用的方法之外的几种典型计算理论。通过对国内研究方法的探讨,可知运用半经验半理论方法计算裂缝宽度尚有一定的不足,仍需进一步改进。

| Abstract: | Crack width calculation of Concrete component is complicated. Scholars at home and abroad have all thrown large amount of theory into studying its calculation method, and have developed many theories for many years. The article mainly introduced several representative methods except the concrete norm's. Through discussing of these methods,the semi-theory and semi-experiment still need further improvement. |
