钢筋混凝土结构的裂缝控制

Cracking Control of Reinforced Concrete Construction

钢筋混凝土的裂缝控制问题是建筑工程中很重要的问题之一 ,特别是最近 2 0年来 ,泵送商品混凝土获得广泛应用之后 ,混凝土均质性有了很大改善的同时 ,裂缝控制技术难度大大增加了 ,本文是在大量建设实践和现场实验研究基础上 ,概述了变形作用引起裂缝的原因 ,约束变形特征 。

Cracking Control of Reinforced Concrete is one of the most important problems in civil engineering,specially after development of pumping concrete,as increased uniformity of concrete,as more difficulty of cracking control.On the bases of large amount of cracks treating experience and exprimental research,the author has summarized reason of cracking、restraint deformation characteristic、design principle“to resist” and “to release” and put forward comprehensive method for cracking control. 〔
