| Abstract: | In the process of constructing long-diameter cost-m-place piles ,there are often various defects. The serious isolation, broken piles and superfluous sediment at the pile bottom must be disposed, and their disposing effect must be newly detected and evaluated. The authors introduce the disposing project, detecting mains of acoustic transmission method and detecting results of certain bridge piles h this paper, and discusse physical characters of defects and basic features of detecting curves befor disposing and after disposing. |
