预制空心板混凝土裂缝的预防与处治

Prevention and Solution of the Fissure on Prestressed Concrete Cored Slabs

混凝土作为一种抗压不抗拉的桥梁刚性建筑材料,抗拉强度只有抗压强度的1/10,其裂缝产生的原因极为复杂。要根本解决混凝土的裂缝问题,还要从裂缝的形成原因入手。正确判断和分析裂缝的成因,是有效消除裂缝的最佳途径。

As a special bridge rigid construction material,the anti-draw intension of concrete is only 1/10 of that of anti-press intension,thus make its cracking cause more complicated. To solve the problem,we should start with the cause. Correctly judging and analysing the cause is the best solution to avoid cracking.
