桥梁工程施工中大体积混凝土裂缝成因及处理措施研究

Research on the Causes and Treatment Measures of Mass Concrete Cracks in Bridge Engineering Construction

道路工程发展得越来越快,而桥梁工程是其重要的组成部分。根据我国对大体积混凝土的界定标准,现在大多数桥梁都会使用大体积混凝土。与普通混凝土相比,大体积混凝土产生的裂缝更多,维修也更复杂。文章为了探讨大体积混凝土开裂的成因,以具体的工程案例为依托,分析可能存在的风险因素,并从混凝土水热化、外界气温变化、沉降施工等方面提出裂缝的针对性处理措施,以供参考。

Road engineering is developing faster and faster,and bridge engineering is an important part of it. According to the definition standard of mass concrete in China, most bridges now use mass concrete. Compared with ordinary concrete, mass concrete produces more cracks and is more complicated to repair. In order to explore the causes of mass concrete cracking, this paper analyzes the possible risk factors based on specific engineering cases, and proposes targeted treatment measures for cracks from the aspects of concrete hydrothermalization, external temperature changes,and settlement construction for reference.
