This technique does apply while statically testing a vertical compression pile using vibrating wire strain gages. The aim of this technique is to measure the responses to load in the test pile in terms of relative strain responses throughout the pile length. Such pile shall be subjected to a standard ML (maintained load) static load testing procedure and shall be instrumented to ensure that the load distribution along the pile lengths could be monitored during the test.

This static load testing procedure to be employed, shall be ASTM D1143 (compression) and D 3689 (tension).
