Pile Testing – Papers

Handbook on Pile Load Testing
Federation of Piling Specialists.

“Pile load testing provides an opportunity for continuous improvement in foundation design and construction practices, while at the same time fulfilling its traditional role of design validation and routine quality control of the piling works. In order to achieve this improvement, data from pile tests has to be collected and analysed to enable the piling industry, both individually and collectively, to make the best use of resources. To justify its cost to the industry, pile testing must have a value. The magnitude of this value will be increased through a better understanding of the process and its benefits.In this handbook the Federation of Piling Specialists aims to provide guidance on issues that should be considered to enable better planning, specification and execution of pile tests, thereby increasing the value of the testing process…”.

Static testing in deep foundations
Federal Highway Administration (FHWA)

“A static load test is conducted to measure the response of a pile under applied load. Conventional static load tests include…”.

ASTM D 4945–08 “Standard Test Method for High-Strain Dynamic Testing of Deep Foundations”

“This dynamic test method covers the procedure for applying an axial impact force with a pile driving hammer or a large drop weight that will cause a relatively high strain at the top of an individual vertical or inclined deep foundation unit, and for measuring the subsequent force and velocity response of that deep foundation unit. High-strain dynamic testing applies to any deep foundation unit, also referred to herein as a “pile” which functions in a manner similar to a driven pile or a cast-in-place pile regardless of the method of installation, and which conforms with the requirements of this test method”.
