摘要
结合工程实例,从水泥水化热、约束条件、外界气温变化、收缩徐变变形等方面分析了超厚混凝土施工裂缝产生的因素,并对超厚混凝土施工中材料、外加剂、施工工艺等控制措施作了阐述,以有效控制裂缝的产生。
Combining with the engineering cases, the paper fully analyzes the factors leading to cracks on the super-thick concrete construction from the cement hydration heat, restraints, external temperature changes, and shrinkage creep deformation, and illustrates some controlling meas- ures for materials, additive agents, and construction craft in the super-thick concrete construction , so it is effective to control cracks.
