大体积混凝土在桥梁结构中的应用越来越广泛,混凝土作为路桥施工中常用的建材,其质量直接影响到工程的质量。在应用混凝土材料进行建筑结构、公路、桥梁及隧道等工程建设中,人们也发现,混凝土开裂是最常见的一种病害,裂缝产生原因很复杂,可能是因为材料的质量问题,还有一些施工中的操作过程。本文对如何防治路桥施工中裂缝的产生技术作简要的分析,以期为业界技术研究人员提供一定的参考。 The application of mass concrete in bridge structures is more and more widely. As a commonly used building material in road and bridge construction, the quality of concrete directly affects the quality of the project. In the application of concrete materials for building structures, roads, bridges and tunnels and other construction projects, people also found that concrete cracking is the most common one kind of disease, the causes of cracks is very complex, probably because of the quality of the material, as well as some construction In the process of operation. This paper gives a brief analysis of how to prevent cracks in the construction of road and bridge construction, with a view to providing some reference for the technical researchers in the industry.
