将超声波检测法应用于隧道火灾后的初砌损伤评定，通过试验研究给出了砼超声波速与砼有关物理力学性能的关系，并对超声波检测常规方法在隧道衬砌火损后的应用给出了评价．
The ultrasonic testing method is applied to the assessment of initial damage after tunnel fire. The relationship between the ultrasonic velocity and the physical and mechanical properties of concrete is given through the experimental study. The application of the ultrasonic testing method to the tunnel lining fire damage is given Evaluation.
