| 摘 要： | 利用回弹－超声和砼碳化测定等综合方法来评估受火灾砼结构的损伤情况．以未受损砼结构构件上测得的检测参数为基准点，通过回弹比和超声比来评估砼表面温度，推定灾后砼强度等级；并按４个层次来评估结构砼的受损情况．

| Abstract: | Based on high tempreature experiments, a comprehensive method of ultrasonic flaw-resilience and concrete carbonisation determination is applied to evaluate fire damage of concrete structure. With detecting parameters obtained from undamaged members of concrete structure as datum marks, the author evaluates surface temperature of concrete by resilience ratio and ultrasonic ratio; and infers strength grade of concrete after fire; and evaluates the damage in four levels. These may serve as a reference for detecting concrete structure damaged by fire. |
