      The analysis results show that the crushing effect of concrete beam segments increases with the increase of aperture and the decrease of hole spacing According to the crushing effect of the beam segments, the aperture of 50#x2009;mm, the spacing of 400#x2009;mm, and the hole end (edge) spacing of 250#x2009;mm were determined as the optimal hole layout scheme

  • Concrete crushing based on the highvoltage pulse

    Based on the optimal scheme of 50 mm hole diameter and 400 mm hole spacing, the influence of hole end distance and edge distance on the crushing effect of the concrete beam section was investigated The end distance of the hole is the same as the edge distance, which has three levels of 200 mm, 250 mm and 300 mm
