EFFECT OF PILE DRIVING ON VIBRATIONS TRANSMITTED IN THE SOIL

Abstract

Vibrations are transmitted in all directions from a source of disturbance like pile driving. These may cause damage to structures. In this investigation decay of vibrations was measured with distance. from a source of disturbance. Ah 11 cm. pipe was driven upto 9 meter depth at one site and 6 meter depth at another, A trench was dug at a predetermined distance from this source of disturbance and its effect in inter-cepting the vibrations was also studied. It was later filled with different vibration absorbing materials e.g, loose sand and saw dust. Their effect in intercepting the vibrations was also studied. It was found that empty trench was most effective in reducing the vibrations
