ABSTRACT:
The subject invention pertains to a method and apparatus for testing the static load-bearing capacity of a pile. In an embodiment, one or more load devices for applying a test load can be disposed within a pile such that a pile element can be above the load device, and a pile element can be below the load device. Upon applying a test load, the pile element above the load device and the pile element below the load device tend to separate. The test loads applied to the pile can be controlled in response to the magnitude of the test load, the combined settlement rate of the pile elements, the displacement of the pile elements, and the compression of the pile elements. A test regime can continue until a programmed regime is completed or a fail-safe trigger event occurs.
