The reaction piles are set up in the check pile at a minimal distance, And so the response piles tend not to influence the loading from the test pile. On a standard compression take a look at, the reaction beam is cribbed a distance off of the bottom to accommodate the check jack and load cell between the test pile and The underside of your test beam. The compressive load is then placed on the pile in the take a look at jack reacting against The underside in the beam. The prestress force over the response piles hold the beam from rolling.
