基于统计分析的冻融循环作用下钢筋与混凝土粘结强度研究综述
摘要：粘结力的存在是钢筋与混凝土共同发挥作用的基础，而冻融循环作用会对二者的粘结强度产生影响。依据已有的冻融循环作用下钢筋与混凝土粘结强度试验数据，通过拟合公式分别分析了冻融循环次数、混凝土抗压强度、混凝土相对保护层厚度以及钢筋直径对粘结强度的影响。最后建立了一个统一的包括多种影响因素在内的粘结强度预测模型，并通过与实际试验数据相比较发现拟合程度较好。
关键词：冻融循环；混凝土抗压强度；相对保护层厚度；钢筋直径；粘结强度；

Research review of bond strength between steel bar and concrete in freeze-thaw cycles based on statistical analysis
Abstract: The existence of bond is the basis for reinforcing bar and concrete to work together, and the freeze-thaw cycles will affect the bond strength of them. According to the existing experimental data of bond strength between reinforcing bar and concrete under freeze-thaw cycles, the influences of freeze-thaw cycles, concrete compressive strength, concrete relative protective layer thickness and reinforcing bar diameter on bond strength were analyzed by fitting formulas. Finally, a unified bond strength prediction model including a variety of influencing factors was established. By comparing with the actual test data, it is found that the fitting degree is better.
Keywords: freeze-thaw cycle; compressive strength of concrete; relative protective layer thickness; reinforcing bar diameter; bond strength
