HOW TO DESIGN FRICTION PILES ?

Dear Friends ,

Good afternoon.

Today we shall have a look at the primary considerations for calculating the basic parameters of a friction pile.

But before we take up the discussions , let us have a look at this picture :

Now ,a look at the Friction piles :

Whenever, the depth of the hard strata is so deep that boring up to that depth is either not economical or it takes too much time , it is suggested to go for Friction Piles.

The load is carried by the friction developed between the concrete surface and the surrounding soil
