| Abstract: | From the point of kinematics and dynamics,the author analyses the propagation rules of stress waves in concrete,namely time-space relations,wave amplitude attenuation,dispersion effect and characteristics of transmission of reflected waves and acoustic waves.Combining with engineering practices,the author also concluded the main points of low strain detection of integrity of longdiameter underwater cast-in-situ piles,and pointed out that comprehensive and relational utilization of reflected waves method and acoustic wave transmission method can accurately evaluated the integrity of pile shaft and then improve the reliability of detection.6figs.,3refs. |
