Figure 3.15 shows the schematic set up for applying axial compression loads to the test pile using hydraulic jack acting against a platform. The platform was comprised of steel sheets and concrete boxes having total weight of 500 kN supported by upper cross H-beams. The reaction beam or test beam was support by lower cross H beams supported by concrete box that distributed the total weight of the platform to the surrounding soil. The vertical load was applied to the test pile through a 600 kN capacity hydraulic jack. A 500 kN capacity proving ring was inserted between the jack and the reaction beam to measure the applied load. The ball bearing was inserted between the proving and the reaction beam to ensure the vertical direction of the applied loads from the hydraulic jack. The vertical settlement of the test pile under the applied load was measured using two dial gages, which were connected to two reference beams placed on both sides of the jack. The axial compression tests were performed in accordance with ASTM D-1143, Quick Load Test Method for Individual Piles under Static Axial Compression Load. The load was applied in increments of 10 kN. Each load increment was maintained for 5 min. The load was applied until continuous vertical displacements occurred at a slight or no increase in load. The test program is summarized in Table 3.2.
