随着我国城市轨道交通工程的发展,地铁建设日益重要。在地铁工程建设过程中,大体积混凝土浇注常常会出现结构裂缝,影响工程建设质量,乃至地铁将来能否有良好的安全性能和使用寿命长短的一个重要因素。只有对地铁施工中混凝土裂缝的成因进行细致科学的分析,才能找到预防和控制混凝土裂缝的有效措施。文章是作者结合多年的工作经验和以成都地铁为例,就地铁工程混凝土裂缝问题进行简要的阐述和分析,供参考!
With the development of China’s urban rail transit project, the construction of subway is increasingly important. In the subway construction process, mass concrete pouring often appear structural cracks, affecting the quality of construction, as well as the subway in the future whether there is a good safety performance and service life of an important factor. Only by careful and scientific analysis of the causes of concrete cracks in subway construction can we find effective measures to prevent and control concrete cracks. The article is the author combined with many years of work experience and to Chengdu subway, for example, on the subway project concrete cracks briefly described and analyzed for reference!
