Pile Integrity Test Results

Pile integrity Test Procedure


The purpose of this study was to test the test piles under Routine load. The design load on the pile is 43.0 T as computed based upon static analysis. The pile is to be tested for vertical compression up to 1.5 times the design load (65.0 ton) or failure, whichever is earlier. The test results have been analyzed to evaluate the safe load on test pile.

The test pile is RCC Bored-cast-in-situ of 600 mm diameter and 11.2m length.


            The procedure for the test was in general accordance with IS:2911 (Part- IV) -1985. The reaction for applying compression load on the test pile is taken by kentledge method to transfer the load on test pile by sand bags. The test load was applied on the pile top by means of a hydraulic jack using plate girders with synchronized electric pumping unit.

 The load is measured with the help of a calibrated load gauge attached to pumping unit. The test was carried out by applying a series of vertical downward incremental loads, each increment being of about 15% of safe load on piles. Displacements were recorded by means of dial gauges of

0.01 mm sensitivity, four nos. of dial gauges which are provided on the pile top to record settlement.


 Vertical Compression Pile Load Test

 As per IS:2911 (Part-IV)-1985, the final load (1.5 times of safe design load) on the pile subjected to compression should not exceed the total settlement of 12mm.


 The load settlement curve for Routine pile load test on Pile is presented in fig. no.1.

 As per the Routine pile load test results, the total settlement is to about 2.65 mm for a total applied load of 65.0 ton.


 As per IS-2911 Part IV, we recommend that a design load of 43.0 Ton may be used for 600mm diameter & 11.2m length pile.
