The ob ject test piles ha ve instrum ents suc h as strain ga uge and extensom eter see fig.

Apile analysis of the axial capacity of driven piles. The pile functions as a short column, hence the rock may be stronger than the steel for the maximum design load that can be applied. Jan 15, 20 for that reason, most commonly, pile foundations are of three main types based on structural behavior. End bearing piles these piles transfer their load on to a firm stratum located at a considerable.
