Automatic static load testing for piles

摘要

There is disclosed a method and apparatus for testing the static load-bearing capacity of a pile, wherein a test load is applied to the top of the pile (2) by way of a jack (1) braced against a reaction member (3) and the magnitude of the test load and the resulting displacement of the pile are measured and communicated to an electronic computer (7). The electronic computer (7) issues control signals to the jack (1) in response to the measured magnitude of the test load so as to apply a predetermined regime of test loads to the top of the pile (2). By automatically monitoring the applied test load, it is possible to maintain a desired load with a high level of accuracy for an extended period of time without the need for operator intervention.
