Based on the corresponding relationship between penetration resistance value and the initial, mid, or late stages of setting period, the disturbance-resistant performance of concrete was studied by ultrasonic method, the change of comprehensive strength of the initial, mid and late stages, and disturbance mechanism were analyzed. On this basis, three methods were used to improve the disturbance-resistant capability of concrele-shortening the disturbed period by adding set-controller, reducing surface cracks by adding crack-resistant and toughening agent, and increasing self-healing rate by adding self-healing agent By means of different ratio of the above-mentioned three kinds of functional additives, orthogonal method was used to identify the optimal proportioning of disturbance-resistant a-gent Disturbance-resistant agent of reinforced concrete for bridge was developed,that were 6% of set-controller, 9% of expansion agent and 0.18%(800g/m3 )of crack-resistant and toughening agent%在定义混凝土贯入阻力值与凝结初期、中期及后期对应关系基础上,利用超声法对混凝土凝结阶段受扰动后强度变化进行分析,并时桥梁加固混凝土的抗扰动机制进行研究；在此基础上,利用自制调凝型功能外加剂、抗裂增韧外加剂、自愈合功能外加剂提高混凝土的抗扰动性,即缩短混凝土早期受扰影响比较大的时间段(简称受扰期)、减少表面裂缝、提高受扰混凝土自行修补内部微裂纹以恢复强度性能的能力(简称自愈合性)；利用正交试验分析3种改善途径的复合效应,研制出不中断交通桥梁加固混凝土功能外加剂的最佳配比:调凝型功能外加剂6％、自愈合功能外加剂9％、抗裂增韧外加剂0.18％ (800g/m3).
