Execution of Compressive Tests
9.4.1
Compression Test Load System
The principle system for axial compression load test is to apply a vertical load to the test pile
using hydraulic jack, getting reaction force from other bored piles which are both sides.
Bored pile axial loading test system is based on getting reaction force from the beam that will
be made installation to the reaction bored piles loading the test pile in the axial direction.
From the three bored piles of the same direction, two are called reaction piles in the edge
and pile in the middle is called test pile.
Test beam must be fixed between two reaction piles and stability of loading system shall be
ensured under maximum test load to be applied. Load will be applied by means of hydraulic
power pack unit connected to the hydraulic jacks. Pressure values corresponding to the
scheduled loads will be adjusted by means of calibrated manometers.

Test beam will be prepared with two 800mm pipe which are put under the test beam and
inside the reaction piles. These pipes will be fixed inside the reaction pile’s steel gauge
overlaps and will be welded. Hydraulic jack will be accomodated between test beam and
steel test plate which was fixed on the test pile.
9.4.2
Test Pile Head Preparation
Before commencement of the test, this is need for the preperation head of test pile, which
shall be broken at project level. In this stage, it is necessary to reach strong concrete. Then, if
necessary the required level of test pile can be provided by casting additional concrete. All
steel gauge overlaps must be fixed stirrup re bars up to top level, before concreting.
According to additional concrete sampling result, test can be erected after 7 days.
If test pile defined before construction, steel gauge overlaps shall be fixed all length with
stirrups, and concrete casting shall be continue come to fresh concrete. After this process no
need to breaking pile head and casting new concrete.
9.4.3
Test Location
The test location shall be as illustrated in Figure-1

Test Pile and Instrumentation
Test pile will be of 1000 mm diameter with toe level at 96.983 m. Its construction will be
done from the working level at 106.983 m. The shallowest base will be at the same level of
the original cut-off level of 106.983 m, so that the displacement and corresponding friction
resistance up to this depth can easily be differentiated for the accurate representation of the
performance of the original 10 m long pile from 96.983 to 106.983 m.

Reaction System
The following photo and the enclosed drawing illustrate the test set-up planned to be used
for the full scale loading tests.

Loading System
The load shall be applied by means of hydraulic jack having a capacity of 500 kN. The jack is
connected to control unit where the hydraulic power is generated by electricity and also
where the pressure in the system (and jack) is monitored by built in manometer(s). The
picture of the loading system is presented below.
9.4.7
Settlement Readings
The settlements shall be read by two (2) micrometers connected to reference beams,
independently supported by steel rebar. Every reaction piles displacement shall be read by
one micrometer connected to reference beams. The micrometers have a range of 0-50 mm
and precision of 0.01 mm. The settlement monitoring setup is illustrated below.

Loading Procedure
Standard Loading Procedure with two cycles shall be applied.
i.
•
First Cycle;
Load the pile 25%, 50%, 75% of the pile working load (WL) and taking four readings for half
an hour.
•
Maintain 100% of the WL for 6 (six) hour and taking 15 readings.
•
Remove the applied load in decrements equal to the loading increments, allowing 15 min.
between decrements.
•
ii.
Maintain 0% of the WL for 2 (two) hours and taking 7 readings.
Second Cycle;
•
Reapply load to 50% of WL and maintain the load for 30 min. and 4 readings.
•
Apply additional 50% of WL and maintain the load for 30 min. and 4 readings.
•
Maintain 100% of WL for 12 hours.
•
Remove the applied load in decrements equal to the loading increments, allowing 15 min.
between decrements.
•
Maintain 0% of the WL for 2 (two) hours and taking 7 readings.
