目前,随着交通基础建设迅猛发展,各地兴建了大量混凝土桥梁。在桥梁建造和使用过程中,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。如果采取一定的措施,很多裂缝是可以避免的。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缝,本文尽可能对混凝土桥梁裂缝的种类及其产生原因作较全面的分析、总结,以便设计、施工找出控制裂缝的可行性办法,达到防范于未然的目的。
At present, with the rapid development of transportation infrastructure, a large number of concrete bridges have been built around the country. 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. If you take some measures, a lot of cracks can be avoided. In order to further strengthen the understanding of the cracks in concrete bridges and try to avoid the occurrence of more damaging cracks in the project, this paper analyzes and summarizes the types of cracks in concrete bridges and their causes as much as possible so as to find out the control cracks in design and construction The feasibility of measures to achieve the goal of guarding against the unfortunate.
