Pile Lateral Loading Test
The main purpose of the lateral loading test is to confirm the design assumptions and the bored pile load capacity. This test is also show the actual safety factor applied for the piles.
Test Setting-up
The lateral loading test method is deadman support. The load will produced by hydraulic jack placed behind the test pile and horizontally support by deadman. The deadman has sufficient capacity to support the load to avoid excessive deflection under load with sufficient clearance between the bearing plate and the test plate at the test pile to provide for necessary hydraulic jack.

Apparatus for measurement
- Reference Beam
All reference beams will be independently supported with supports firmly embedded in the ground at a clear distance of not less than 2.5m from the test pile and as far as practical from the anchor piles and a supporting block. Reference beam will be sufficiently stiff to support the instrumentation such that excessive variations in readings do not occur. One end of each reference beam will be free to move horizontally as the beam length changes with temperature variations.
- Dial Gauges
Dial gauges have 50mm travel with 0.01mm precision. 50x50mm2 Glass square will installed perpendicular to the direction of gage-stem travel. All dial gauges, scale and reference point will be clearly marked with a reference number to assist in recording data accurately. Gauges attached to the test pile will be mounted to prevent movement relative during the test.
Pile Lateral Movement
The lateral movement of the test pile will be measured to accuracy 0.01mm using two dial gauges mounted on the reference beam 90° apart with their stem perpendicular to the longitudinal axis of the test pile and bearing against the sides of the test pile.
Test Procedure
The loading procedure in this test is the cyclic loading. The maximum loading is 2 times of design load. Loading sequence is following the Cyclic Loading procedure. Reading procedure follows the Standard Measurement Procedure.
