| Abstract: | The method of ultrasonic tests was employed to investigate the strength and defects in circular reinforced concrete poles,and mechanism of the crack emerged on the circular reinforced concrete was discussed,whereby acguining the fitted equation of the strength.Then the relevant formulas for the depths of longitudinal circular cracks were derived.Based on this,a specific engineering testing example for strength and the depth of cracks of circular reinforced concrete pole was given,and the residual service life time was obtained.It is great significance for similar engineering in concrete quality detection,health performance assessment and service life prediction. |
