Pile capacity testing

    Abstract

    As there is still uncertainty in accurately predicting the performance of piled foundations based upon design calculations there remains a need to test piles. Several methods of pile testing are available some that have been in common usage for many years others that are relatively recent developments. Static pile testing is a well understood and simple test technique that has been in use for many years. This approach has the benefit of directly producing test results but is hindered by the increasing size of associated testing infrastructure as pile capacity increases. A recent variation of classic top down static testing is bi-directional testing which relies on the incorporation of a specialised loading jack or jacks in the pile shaft at some depth below ground surface. This technique has the ability to apply test loads that greatly exceed those possible in other pile test types. Alternative pile testing techniques come in the form of rapid and dynamic load tests that have the benefit of quick testing and reduced testing infrastructure but require more complicated analysis and interpretation techniques due to the rapid/dynamic nature of the tests.
