混凝土裂缝的施工控制

Construction control for concrete cracks

钢筋混凝土结构裂缝的成因是复杂的和多方面的 ,主要原因有以下两个方面。其一是混凝土内部产生拉应力而导致裂缝 ;其二是混凝土材质方面的原因。本文主要讨论的是通过施工控制方法 ,消除或减少混凝土裂缝产生的原因 ,从而控制混凝土拉应力的产生 ,以达到减少混凝土结构出现裂缝的目的。

The reasons for the crack of concrete structure are complicated and many sided, but the main cause is following two sides. One is internal force which pulls the crack, the other is the material of concrete. In this paper, it is mainly discussed that how to dispel or reduce the factors which cause concrete cracks, so that the tension force in concrete can be controlled, and the concrete cracks will be reduced.
