| 中文摘要: |
| 对混凝土在火灾条件下的热像平均温升、抗压强度、超声波速和损伤深度进行了检测,获得了混凝土热像平均温升、抗压强度、超声波速和损伤深度随着温度变化的规律,并对影响混凝土热像平均温升和超声波速的因素进行了分析,为混凝土结构火灾损伤程度的现场检测提供了一种科学的技术方法。 |
| 英文摘要: |
| The average temperature rising of infrared therma l images, compressible strength, ultrasonic velocity and fire damage depth were te sted under fire condition for concrete. The general variation behaviors with tem perature were gained. The factors affecting the average temperature rising for i nfrared thermal images and the ultrasonic velocity were analyzed. |
