Testing Details

ABOUT:

In the Spring of 2015, Ensoft finished the construction of their

own Pile Testing Setup. The setup consists of two 24-in drilled

shafts with a 17.5-ft penetration, and a center to center distance

of 24-ft. These shafts support the reaction loads for an 18-in

‘Axial-Test’ shaft, located exactly at the midpoint of the 24-ft

span, with a penetration of 13.5-ft. The shafts were designed to

handle both axial compression and tension, on the ‘Axial-Test’

shaft. Additionally this design can accommodate lateral testing of

the reaction piles using a high-strength steel threadbar to pull

the shafts toward each other. The purpose of this construction,

was to supplement the existing short course curriculum with

physical testing demonstrations for the participants.

ABOUT (CONTINUED):

The in-situ conditions consist of roughly 6-ft of Stiff Clay

(cohesion = 2500psf to 5000psf) on top of Weathered Limestone-

Weak Rock (comp. strength = 200psi). Each shaft is instrumented

with Strain Bars fabricated in-house by Ensoft’s engineers. The

center shaft has twelve strain bars (mixture of optical and electri-

cal resistance) tied to the rebar cage at documented depths (see

page 4).

LIVE DEMONSTRATIONS:

1. Instrumented Axial Load Test:

A live demonstration of an Axial Compression test will be per-

formed during the reception. Real-time measurements of applied

load, displacements, and strains, from both the ’Test’ and

’Reaction’ piles will displayed as the test progresses. Due to time

limitations, the test will only consist of several load stages (elastic

loading), in order to give attendee’s an accurate depiction of what

to expect and look for during testing procedures (weather per-

mitting).

2. Non-Destructive Testing:

Sample equipment and testing techniques demonstrated for non-

destructive testing — to include Cross-hole Sonic Logging (CSL),

and Pulse Echo Testing.

3. Other:

A pile testing frame will be set up for visualizations of axial test-

ing procedures smaller-sized piles (loads of <25-kips). Lateral

test demonstration will be performed on Tuesday, 11/29/16, for

those participant’s of the short course only.
