REPORT ON LAND GEOTECHNICAL INVESTIGATIONS FOR THE
PROPOSED COAL BERTH CB-3 & 4 AT ENNORE PORT.
INTRODUCTION:
Soil Investigation work at Ennore Port Limited for the proposed Coal Berth
CB-3 & CB-4 at Ennore Port, Chennai has been carried out by M/s. C & C
Consulting Firm, Kolkata vide Order No. EPL/OP/41/022 dtd. 24.05.2013 of
M/s Ennore Port Limited.
The main objective of the investigation is to ascertain the sub-soil condition at
the proposed at site and to make foundation investigation of the proposed
structure based on the findings of field and laboratory investigation. The
investigation was carried out by sinking ten nos. of deep Boreholes at different
locations with depth of 50 m below existing GL. The test location Plan & RL
was handed over by M/s. Ennore Port Limited to M/s. C & C Consulting Firm.
This report has been prepared on the basis of both Field and Laboratory
investigation and makes recommendation for the foundation to be adopted for
the proposed Wharf Structures together with the Bearing Capacity.

BORING :
Each borehole of 150mm dia was advanced into the soil by Shell & Augur
technique. Stabilization of boreholes was achieved by flush jointed seamless
casing as well as bentonite slurry.
The ground water table was observed in the borehole at the end of completion
of the borehole and after 24 hours of completion. The ground water table thus
observed is tabulated above.

SAMPLING:
Disturbed samples were taken at suitable intervals of depths and at changes of
stratum in order to examine physically the nature of all strata. They were
collected from the Auger and the barrel of the split spoon sampler after the
Standard Penetration Tests. The depth wise locations of all the disturbed and
samples recovered from split spoon sampler have been furnished in the bore log
data sheet. After collection of samples, all the samples were carefully preserved
and sealed.
In addition to that Water Samples were collected from all the boreholes after 24
hours of completion, to ascertain the Chemical Properties.
IN SITU TESTS:
Standard Penetration Test (SPT):
Standard Penetration Tests were conducted as per IS: 2131 (1981) within each
borehole at suitable interval of depths as shown in the borelog data sheets. The
tests were done with the standard split spoon sampler as per IS: 9640 (1980).
The ‘N’ values were obtained by counting the number of blows required to drive
the spoon from 15cm to 45cm.

LABORATORY INVESTIGATION:
The soil samples from the 10cm diameter sampling tube were extracted in the
laboratory by pushing out the soil core by employing an extractor frame. Thecore was jacked out in a direction that corresponded with the soil movement
within the tube during sampling.
In general, the following tests were carried out on representative samples
of difference strata following IS Code of practices given in brackets:
Bulk Density (IS 2720 Part VII)
Natural Moisture Content (IS 2720 Part II)
Atterberg Limits (IS 2720 Part V)
Sieve Analysis (IS 2720 Part IV)
Consolidation test (IS 2720 Part XV)
Determination of Shear strength
Chemical tests on soil & water samples
Atterberg Limits (LL & PL)
and Natural Moisture Content:
Liquid limit, plastic limit and natural moisture content of the Silty clay samples
were determined (a) to classify the soil by the unified soil classification system
and (b) to qualitatively assess their consistency and compressibility.
Triaxial Test:
These tests were conducted on the clay samples to determine their shear
strength. All such the tests were carried out under un-drained conditions. The
cell pressures used for un-drained tests on clay samples where 0.50, 1.00 and
1.50kg/sq.m. The samples were tested in such case under quick conditions
@1.25mm/min. and were loaded upto a maximum of 20% axial strain.

Consolidation Test:
Consolidation tests were run in floating ring type oedometers, under standard
load increment ratio of 1. Starting from 0.25kg./sq.cm. and going upto 8.00
kg./sq.cm. in general.
Sieve Analysis:
The grain size distributions of some representative samples were determined
from sieve analysis / combined sieve analysis and hydrometer analysis. The
results have been plotted as shown in grain size distribution curves.
Particle Size Analysis:
The grain size distributions of some representative samples were determined
form sieve analysis / combined sieve analysis and hydrometer analysis. The
results have been plotted as shown in grain size distribution curves.

Length of Pile = 45.0 m
For L/D = 20, the effective overburden pressure
pd = 0.95 x 20 x D = 19D
For Φ = 340 , N q = 40.8
∴ Ultimate End Bearing

= 608.5 D3
Skin friction = π D [ 11 x 19D x 1.0 x tan 310+18 x 6.5 x 0.3 + 9.0 x 19D x 1.5
