METHODOLOGY OF CYCLIC VERTICAL LOAD TEST

CONDUCTED ON 600 MM DIA OF TEST PILE

Test Arrangement:

The top of the Test pile was chipped to remove the overflowed concrete and dry Bentonite slurry till to sound

concrete get if required the pile shall be built up to COL. The top of the pile to be finished at cut of level. An

average loading platform of 7.00m x 8.00m was formed using 3Nos ISMB 550 joists as the main beam shall

be placed centrally above the pile top, 15 No’s of ISMB 400 joists will be used as cross / distribution girders.

Required quantities of concrete blocks will be loaded on top of this platform.

The Test load on the pile is 145 MT as mentioned in drawing no: 19200-0102-8310-42-0201, Rev S1. Hence

the total weight of Kent ledge will be 182.00MT (25% extra)

A 30mm steel plate will be placed over the pile top. The 600 MT capacity of hydraulic one jack will be

placed centrally over the pile top in such a way that the centre of gravity of the pile, pile top and the

kentledge shall be co-axial. The gap between the jack and the main beams will be filled using steel

beam/plate as packing material. Datum bars with supports at a distance 4.00 m from the face of the pile will

be placed on either side of pile. Dial gauges will be placed over those datum bars using magnetic bases.

Test Procedure

The cyclic procedure consisted of applying and releasing a large number of unidirectional loads. The time to

complete one load cycle varies from approximately 60 minutes the loading and unloading frequency was

controlled by the capacity of the hydraulic pump and extended length of the ram plunger. After 12”th cycles

from loading frequency was decreased. During 12”th cycle load were applied in every 60 minutes. In

between increment reading will be noted during this cycle using same incremental procedure.

Sustained loads will be applied by incrementally increasing and decreasing the load up to a Final load and

maintaining this load for 24 hours.

Each load increment will be 12.94 MT (approx). Each increment will be maintained for 60 minutes or till the

rate of settlement of the pile top was less than 0.1mm in 30 minutes or 0.2mm in 1hr which will be occurred

first. After every loading and maintain 60 minutes the load shall be released and reading shall be recorded at

15minutes. After that next increment to be applied. This is to be followed for every increment and

decrement. The maximum load of 145.00 MT was maintained for 24hrs and hourly readings shall be noted.

At the end of 24hrs unloading shall be done gradually till the load was released. After releasing the load,

reading observation to be recorded at least for 2 hrs.


22/30

TEST RESULTS

The results of the load test are tabulated in table – 1 & 2 and the load settlement curve presented in Fig – 2

From the curve it may be observed that the maximum settlement at 145 MT was -------mm and net

settlement was ------mm as against a permissible settlement of 12mm as per IS code 2911 – part IV.

CONCLUSION

Since the total maximum settlement …….. at the load ……is within/without limits specified in

IS2911 – part IV – 1985 the pile is safe for a design load of …… MT.
