Tension Piles
Tension piles is one of piled foundations which bored in soil to resis uplift forces. Tension Piles structures such as tall chimneys, transmission towers and jetties can be subject to large overturning moments and so are often used to resist the resulting uplift forces at the foundations. In such cases the resulting forces are transmitted to the soil along the embedded length of the pile. The resisting force can be increased in the case of bored piles by under-reaming.
