摘　　要：本文采用了全年最大环境温差、混凝土永久性干缩值和混凝土永久性限制膨胀率为依据对钢筋混凝土永久性缝间距进行了计算分析,并提出了提高混凝土抗裂能力的有效措施。The permanent space between seams of reinforced concrete was calculated based on the annual maximum environmental differential in temperature,concrete permanent shrinkage value and concrete permanent limited expansion ratio.And the efficient measurement for improving concrete anticrack performance was provided.

关 键 词：钢筋混凝土 抗裂计算 当量温差 永久性缝问距
