桥梁建造和使用过程中,有关因出现裂缝而影响工程质量甚至导致桥梁垮塌的报道屡见不鲜。混凝土开裂可以说是“常见病”和“多发病”。经常困扰着桥梁工程技术人员。其实,如果采取一定的设计和施工措施,很多裂缝是可以克服和控制的。为了进一步加强对混凝土桥梁裂缝的认识,尽量避免工程中出现危害较大的裂 During the process of construction and use of bridges, it is not uncommon for reports of cracks affecting the construction quality and even the collapsing of bridges. Concrete cracking can be described as “common disease ” and “frequently-occurring disease ”. Often bothering bridge engineering and technical personnel. In fact, if we adopt certain design and construction measures, many cracks can be overcome and controlled. In order to further strengthen the understanding of concrete bridge cracks, try to avoid the construction of a greater risk of cracking
