| Abstract: | On the basis of the theory of elastic wave,the method of mathematical statistics,the non-destructive inspection for concrete precast pile before the use by using the method of elastic wave is introduced briefly,meanwhile,the relation between longitudinal wave speed of pile body concrete and intensity is analysed,also,a method of judgement for the defect location of a pile body and its property is introduced in this paper. |
