  • Moldavite Stone Bracelet By Stones Desire

    As vibration-induced liquefaction occurs, crushed stone backfill is placed around the vibrator, leading to the development of a stone column that is approximately 1 m (3 ft) in diameter. The stone column increases the effectiveness of vibration transmission, and facilitates drainage of excess pore water pressures as densification occurs. The Figure 11-5.(one day). Thus, the vibration intensity should not exceed this same percentage of a particle velocity of 5. 0 in. sec limiting values of vibration are, therefore, 0. 25 and 0. 5 i.11. sec, respectively.
