Embodiment
[0053] Using the wave detection device consisting of a data collection device, a wave detector and an elastic wave excitation device, the elastic wave data are collected for the rock-fill concrete structure of the dam when the maintenance age is 2d, 7d, 14d, 28d and 90d.
[0054] Wherein, the distance between the detector and the elastic wave excitation device is 1 m. During the detection process, the elastic wave excitation device-geophone array is set along the upstream and downstream direction of the dam. After the elastic wave data is collected at the first detection point, the wave detection device is placed along the Translate in a straight line, and the distance of each movement is 1m. Collect the elastic wave data corresponding to the detection point after each movement.
[0055] After the detection along the above detection line is completed, the wave detection device is translated in the direction perpendicular to the upstream and downstream, and after the translati...
