桥梁工程大体积混凝土裂缝分析

Mass concrete crack analysis in the bridge project

从水泥水化热、混凝土收缩、外界气温湿度等方面分析了桥梁结构中大体积混凝土产生裂缝的原因,并从水泥的品种及用量、外加料及外加剂、设计、施工等方面提出了防止裂缝的主要技术措施,以保证桥梁工程的使用质量。

It analyzes the reasons generating mass concrete crack in the bridge structure from the aspects of the heat of cement hydration, concrete contraction; external temperature and so on, and brings forward the main technical measures to prevent crack from the aspects of the breed and use level of cement, impressed material and additional agent, design, construction and so on, which will assure the operation quality of bridge project.
