PILE INTEGRITY TEST

DESCRIPTION

Fondation piles are generally controLLed through static Load

tests in order to get their bearing capacity by measuring the

pile settlement due to the static Load being applied. This kind

of test allows to analysis the response of the pile-soil

system over a wide range of deformation that can reach the

collapse conditions.

The need to reduce testing time and costs has brought to

the diffusion of a number of different non destructive

methodologies:

• cross-hole

• dynamic pile test

Sonic integrity, instrumented hammer and mechanical

admittance methods may be classified among low strain

dynamic tests and they enable to verify the shape and the

length of the pile as well as any defect. "Case" testing

instead is a high strain dynamic method which gives

indication of the pile limit load.
