摘　　要：论文着力解决硬化混凝土骨料体积稳定性不良造成的损伤难题。分析了病害产生原因,列举了病害是否影响现浇结构安全的检验方法,对检验批划分和抽样数量的确定提出建议。当混凝土骨料体积稳定性不良造成的损伤不影响现浇结构时,提出对现浇结构的修复方法,经过工程实践验证了其具备可行性、易操作性,控制了病害不再反复发作且有效控制了处置成本。This paper mainly studies to solve the problem of damage caused by poor volume stability of concrete hardened aggregate.This paper analyzes the causes of the disease,lists the inspection methods of whether the disease affects the safety of cast-in situ structure,and puts forward some suggestions on the division of inspection batch number and the determination of sampling quantity.Under the condition that the damage caused by the poor volume stability of concrete aggregates does not affect the cast-in-place structure,the repair method of cast-in-place structure is proposed,the engineering practice proves that the method is feasible and easy to operate,and the treatment cost is effectively controlled.
