摘要
通过对比超声波在完整混凝土及缺陷混凝土中的传播,据超声波声学参数的变化判别丹江口工程中裂缝的深度,为后期裂缝修补工作提供依据。
By comparing the characteristics of ultrasonic wave spread in the normal concrete and defective concrete, find out the chang of the characteristics. Obtained crack depth in Danjiangkou Dam, Provide the basis for post-crack re- pair work.
