摘　　要：应用损伤理论对钢筋混凝土界面损伤问题进行理论研究,利用模量损伤的概念,建立了考虑界面损伤条件下钢筋与混凝土的粘结力与钢筋滑移量的关系,数值计算结果与试验结果吻合较好。通过比较不同保护层厚度条件下的连续因子,得到最优混凝土保护层厚度。The theoretical research of reinforced concrete interface damage is studied using damage theory. Based on the concept of modulus damage, the relationship between steel slippage and cohesive force of steel and concrete is built up considering interface damage.The numerical calculated results are consistent with the experimental results. Through comparing continuous factor under different concrete cover thickness, an optimal value of concrete cover thickness can be obtained.
