1. INTRODUCTION
1.1. PURPOSE AND SCOPE
Geo-technical site investigation work for “SOIL INVESTIGATION FOR THE
PROPOSED CONSTRUCTION OF PREPARATION OF DPR FOR DEVELOPMENT OF
VELANKANNI IN NAGAPATTINAM DISTRICT UNDER PRASAD SCHEME.” The
primary purpose of our investigation is to obtain data to develop foundation design
recommendations for the above work. At, first instance, Three boreholes was bored at site.
Client’s representatives selected the locations of borings. To accomplish these purposes, the
following tasks were performed:
1. Detailed soil borings were done up to stratum to explore the sub surface stratigraphy
and obtain soil samples for testing. Field and laboratory tests were conducted to
evaluate the index and engineering properties of the soils
2. Engineering analysis were performed to develop foundation design information for
proposed structure
1.2. THE SITE :
“SOIL INVESTIGATION FOR THE PROPOSED CONSTRUCTION FOR PREPARATION
OF DPR FOR DEVELOPMENT OF VELANKANNI IN NAGAPATTINAM DISTRICT
UNDER PRASAD SCHEME.”
2. FIELD INVESTIGATIONS
2.1. ROTARY BORING
Rotary drilling technique was adapted using Calyx machine in this field. In this
method, boring is effected by the cutting action of a rotating bit that is kept in firm contact with
the bottom of the hole. The bit is attached to the lower end of a hollow drill rod that is rotated
by a suitable chuck. Drilling mud (usually Bentonite) is continuously forced down the hollow
drill rods. The mud returning upwards though the annular space between the drill rods and the
side of the hold bring the cutting to the surface.

2.2. STANDARD PENETRATION TEST
It is now most commonly used in site test. The test measures the penetration resistance
of the split spoon sampler, when it is driven into the soil, at the bottom of a borehole in a
standard manner. The N-value, which is the number of blow required to achieve 300mm
penetration of the soil, indicates the relative density of sand or gravel, the consistency of other
soil such as silts or clays and the strength of weak rocks. The test is described in IS 2131 -
1981. The split spoon sampler is attached to stiff drill rod and lowered to the bottom of the
bore hold. A standard blow consists of dropping a mass of 63.5kg free fall through 750 mm on
to an donut hammer at the top of the rods and ensuing that this amount of dynamic energy is
transferred to the sampler as much as possible.
The number of blows required to achieve each 150mm penetration is recorded for a fall
penetration of 450mm. The initial 150mm penetration is referred to as seating drive and the
blows required for this penetration are not considered as this zone is in disturbed soil. The next
300mm of penetration is referred to as the test drive and the number of blows required to
achieve this fully is termed the penetration resistance or N-value.
2.3. SAMPLING
Soil samples were collected through Split spoon and rock core sample were
collected through single tube core barrel.
3. LABORATARY TESTS
The operations to be performed in the laboratory depend upon the type of the nature of
data required for the problem at hand. In case of cohesion less material, like sand, the
laboratory tests are usually minimum and the design parameters are worked out from field test
data such as form SPT- N value, Core resistance and plate load test data.
In the case of cohesive soils, the programme of laboratory testing can vary from
carrying out simple tests such as unconfined tests to comprehensive study of soil behaviour
using triaxial shear tests and consolidation tests.
Following laboratory tests are conducted.
For Cohesion & cohesionless soil
a) Specific gravity
b) Sieve analysis
c) Atterberg’s limits
d) Natural moisture content

4. FOUNDATION ANALYSIS
4.1 Soil Profile
The profile of the area as observed in the bore hole is given in the chart. The water
level is observed far below. The soil layer up to 27.00m depth SILTY CLAY was obtained.
4.2 Safe Bearing Capacity
The bearing capacity of granular soil depends upon the unit weight and angle of internal
friction of the soil. These two properties of granular soils are determined by standard
penetration tests.
The allowable bearing pressure based on tolerable settlement has been established
empirically by Terzaghi and Peck, 1948 and may be expressed by the equation.
Safe bearing capacity (SBC) = 3.5 (N-3) {(B+0.3)/2B}2 × RW × FD +P
Where
N = Corrected N value N1
B = Width of Foundation = constant 1
RW = Water Correction = constant 0.5
FD = Depth of Factor = constant 1
P = Over Burden Pressure

5 . RECOMMENDATION
The site of “SOIL INVESTIGATION FOR THE PROPOSED CONSTRUCTION OF
PREPARATION OF DPR FOR DEVELOPMENT OF VELANKANNI IN
NAGAPATTINAM DISTRICT UNDER PRASAD SCHEME.” The bore hole
investigation was conducted and SBC was determined.
The site up to 27.00m SILTY CLAY is obtained.
PILE FOUNDATION is recommended for this site.
Note:
The detailed SBC at every 1.50m is mentioned in page no’s. – 11 to 13.
