【Abstract】 The sound-time and sound-amplitude features of various defects in pile foundations are described. The formulas for identifying defects and calculating their longitudinal and transverse sizes are derived by using sound-time and sound-amplitude variance. The programs compiled with the formulas are used for automatically i-dentifying and sizing defects in pile, and the results are reliable.更多还原
