混凝土裂缝的成因有荷载作用引起的裂缝或非荷载引起的裂缝。一般钢筋混凝土在荷载作用下,截面的混凝土拉应变大多是大于混凝土极限拉伸值的,故构件实际上是带缝工作的。除荷载作用引起裂缝外,在水工钢筋混凝土结构中,大部分裂缝都是由非荷载因素引起的。针对混凝土裂缝,只要采取合理的对策和措施,就能避免和缓解裂缝的形成。 The causes of concrete cracks are cracks caused by load or non-load caused cracks. General reinforced concrete under load, the concrete section of the tensile strain is greater than the ultimate tensile value of concrete, so the components are actually working with the seam. In addition to the cracks caused by loading, most of the cracks in hydraulic reinforced concrete structures are caused by non-loading factors. For concrete cracks, as long as reasonable measures and measures taken to avoid and mitigate the formation of cracks.
