Behaviour of jacked and driven piles in sandy soil

Compared with conventional driven piles, the behaviour of jacked piles in sand and/or sandy soil is poorly understood, mainly because of the lack of field experience and a high-quality load test database. In a few field studies on the behaviour of driven piles in sand (Lehane et al., 1993; Chow, 1995), jacking was used instead of dynamic driving

Machine Foundation Vibration Analysis Methods

Whenever the machine vibrates, soil below the machine foundation also vibrates. The mass of soil which vibrates due to machine vibration is termed as in-phase soil mass. Therefore, total mass ( m) is equal to m = mf + ms Where, mf = mass of the foundation ms = in-phase soil mass = it varies from 0 to mf Total mass ( m) varies from mf to 2mf.
