Sep 11, 2019· Working on and compacting granular soils such as sands and gravels are difficult tasks. Due to the composition of sand and gravel, water can enter or leave the voids in them with relative ease. If voids in the sand are filled with water or are completely dry, no forces are holding the sand .
during vibration, compared to a massive probe of the same size. Figure 4 shows how the vertical vibration velocity, measured on the ground surface, varies as a function of the vibration frequency. During probe penetration and extraction, a high vibration frequency (around 30 Hz) is used, which does not cause significant ground vibrations.
