Q. Show the Settlement due to Vibration?

The foundation resting on cohesionless soil and subjected to vibrations will result in settlements of higher magnitude. In sandy soils largest settlement will occur within a range of about 500 to 2500 impulses per minute. This is known as optimum range for vibrations. The impulses produced by the turbo-generators, turbines etc. will be in the optimum range. Generally, the settlement caused by the vibration on clayey deposits are small. Hence, it does not cause any damage to the structure.
