Use of in-filled trenches to screen ground vibration
2018-8-1 At first the characterises of ground vibration and the effects of a coal bottom ash in-filled trench on screening the ground vibration induced by impact piling were investigated experimentally. Free field results show that at a distance of 10 m from the source, the PPV of the vertical wave was 4.41 mm/s while the PPVs of the transverse and longitudinal waves were 2.67 mm/s and 3.36 mm/s respectively.

Vibration frequency, screen inclination of the vibrating ...
2021-3-29 Therefore, the vibration direction angle should be reasonably selected. For difficult-to-screen materials, the vibration direction angle should be taken as a large value. For easy-screen materials, the vibration direction angle should be small; in general, the vibration direction angle of the circular vibrating screen is 90°. The vibrating direction angle of the linear vibrating screen ranges from 30 to 60°, often
