WATER

GROUNDWATER NOT

OBSERVED

GROUNDWATER NOT
ENCOUNTERED

The observation of groundwater, whether present or not, was not possible due to drilling water,
surface seepage or cave in of the borehole/test pit.

The borehole/test pit was dry soon after excavation. However, groundwater could be present in
less permeable strata. Inflow may have been observed had the borehole/test pit been left open
for a longer period.

 

 

SAMPLING AND TESTING

SPT

5,4,10 N=14
30/65mm

Standard Penetration Test to AS1289.6.3.1-2004

5,4,10 = Blows per 150mm. _N = Blows per 300mm penetration following 150mm seating
Where practical refusal occurs, the blows and penetration for that interval are reported
Penetration occurred under the rod weight only

Penetration occurred under the hammer and rod weight only

Hammer double bouncing on anvil

Disturbed sample

Bulk disturbed sample

Field shear vane test expressed as uncorrected shear strength (sy = peak value, sr= residual value)
Pocket penetrometer test expressed as instrument reading in kPa

Thin walled tube sample - number indicates nominal sample diameter in millimetres
Dynamic cone penetration test

Electronic cone penetration test

Electronic cone penetration test with pore pressure (u) measurement
