摘要： 通过对大保护层钢筋混凝土构件的试验研究,建立了裂缝间距的计算模式,提出了含有保护层C的抗裂、裂缝间距及裂缝宽度的计算公式,着重论述了保护层引起的机理,所建议的公式对大小保护层均适用且与试验数据很吻合。

Abstract: According to the experimental investigation of reinforced concrete members of thicker cover, the model for calculating crack spacing is established. The formulas involving cover C for predicting cracking resistance, crack spacing and crack width are presented.Mechanism, especially caused by cover,are discussed. The Presented formulas can be applied to both thiner and thicker cover and are in good agreement with experimental data.
