7.2 Standard Penetration Test (SPT)

This test shall be conducted in all types of soil deposits met within the

bore hole to find the variation in the soil stratification by correlating with

the number of blows required for unit penetration of a standard

penetrometer. This test shall be conducted at 3.0m intervals, (Alternately

SPT and UDS at every 1.5m each shall be carried out), at every change of

strata, at depths wherever undisturbed soil samples could not be

collected and as per the directions of the engineer-in charge. The

starting depth of performing SPT shall be at 1.0m depth max. below

ground level. The depth interval between the top level of standard

penetration test and to that of (next) undisturbed sampling shall not be

less than 1m. The specification for equipment and other accessories,

collection of disturbed soil samples etc shall conform to IS: 2131.

This test shall be carried out by driving a standard split spoon sampler in

the borehole by means of a 650N hammer having a free fall of 0.75m. The

sampler shall be driven using the hammer for 450 mm penetration. While

driving, the number of blows for every 150 mm penetration and the

penetration for every 50 blows shall be recorded. The number of blows

for the last 300 mm drive shall be reported as 'N' value. This test shall be

discontinued when the blow count is equal to 100 and the penetration

shall be recorded. Refusal shall be considered to be met with when the

blow count is equal to 100. At the location where the test is discontinued,

the penetration and the corresponding number of blows shall be

reported. Sufficient quantity of disturbed soil samples shall be collected

from the split spoon sampler for identification and laboratory testing. The

samples shall be visually classified & recorded at the site and shall be

properly preserved and labelled for future identification & testing.

7.3 Sampling

7.3.1 General

a) Sufficient number of soil samples shall be collected for reliable

estimation of soil properties. The samples collected shall be either

disturbed or undisturbed. Disturbed soil samples shall be collected for

field identification and conducting laboratory tests such as sieve analysis,

index properties, specific gravity, chemical analysis etc. Undisturbed

samples shall be collected to estimate physical, strength and settlement

properties of the soil.

ANNEXURE-I


b) All the accessories required for sampling and the method of sampling

shall conform to IS:2132. All disturbed and undisturbed samples

collected in the field shall be classified at site as per IS: 1498.

c) All the samples shall be identified with date, borehole or trial pit number,

depth of sampling etc. It is also essential to mark an arrow pointing

towards the top surface of the undisturbed sample as the soil was in-situ.

Care shall be taken to keep the undisturbed soil samples and box

samples vertically with the arrow directing upwards. The tube samples

shall be properly trimmed at both ends and suitably sealed with molten

paraffin wax at both ends immediately after extracting the samples from

the bore hole/trial pit and suitably capped on both sides.

d) When the contractor fails to collect undisturbed soil sample at a specified

depth, the borehole shall be advanced by 0.50m and shall be performed

with a standard penetration test. The reason for not obtaining the

undisturbed soil sample shall be indicated in the bore log.

e) Precaution shall be taken to ensure that there shall not be any change in

moisture content and disturbance of the soil samples and they shall be

placed in a temporary store at the end of the day's work. All the samples

shall be kept over a bed of sand, jute bags, saw dust etc. and covered

over the top with similar material. The bed and top cover shall be kept

moist till they are properly packed in wooden boxes. The contractor shall

be responsible for packing and transporting of all the samples from site

to the laboratory within seven days after sampling with proper protection

against loss and damage.

f) All the samples shall be suitably packed in wooden boxes using sand, saw

dust etc. all around the samples before transporting to the laboratory for

testing.

7.3.2 Disturbed Samples

a) Disturbed soil samples shall be collected from cuttings and from split

spoon sampler in boreholes at regular intervals to provide complete

description of soil profile and its variation. The samples shall be

immediately stored in airtight jars or polythene bags and labelled with

b) In elevated areas, if superficial material is available in plenty, then bulk

samples from a depth of about 0.5m below ground level shall be

collected to establish all required properties to use it as a fill material.

Disturbed samples weighing about 250N shall be collected at shallow

depths and immediately stored in polythene bags as per IS: 1892. The

bags shall be sealed properly and shall be kept in wooden boxes.

7.3.3 Undisturbed Samples

In each borehole, undisturbed sample (UDS) shall be collected at

regular intervals of 3m (Alternately SPT and UDS at every 1.5m each

shall be carried out) and as directed by the engineer-in-charge. The

starting depth shall be staggered in alternate boreholes. Undisturbed

samples shall be of 50mm diameter and 600mm length. Samples shall be

collected in such a manner that the structure of soil and its moisture

content do not get altered. The specification for the accessories required

for sampling and the sampling procedure shall conform to IS:1892 and

IS:2132. Undisturbed sampling in sand shall be done using compressed

air technique as mentioned in IS:8763. Thin walled sampler shall be used

to collect undisturbed samples by pushing the tube into the soil. The

sampling tube shall have a smooth finish on both surfaces and minimum

effective length of 450mm. The area ratio of sampling tubes shall be less

than 12.5%. However in case of very stiff soils, area ratio upto 20% shall

be permitted.

a) Undisturbed Sampling in Cohesive Soil

Undisturbed samples in soft to stiff cohesive soils shall be obtained using

a thin walled sampler. In order to reduce wall friction, suitable

precautions such as oiling the surfaces shall be taken. The bore hole shall

be cleaned and the depth of sampling below ground level shall be noted.

The sampler shall then be attached to the bottom of boring rods and

lowered into the borehole. The sampler shall be pushed into the clay

layer by hand or by jacking and soil sample of specified length shall be

collected without disturbing the soil. The distance by which the sampler

penetrates into the soil strata shall be checked. Care shall be taken to

ensure that the sampler is not driven too far as this will compress the soil.

The sampler shall be rotated to break the core at bottom of the sampler

and then steadily drawn up.




MECON LIMITED

BANGALORE

ANNEXURE-I


b) Undisturbed Sampling Using Piston Sampler

Undisturbed samples in very loose saturated sandy & silty soils and very

soft clays shall be obtained by using a piston sampler consisting of a

sampling cylinder and piston system. In soft clays and silty clays with

water standing in the casing pipe, piston sampler shall be used to collect

undisturbed samples. During this method of sampling expert supervision

is called for. The interior surface of the sampler shall be smooth, clean

and corrosion resistant. Its cutting edge and the ring seals shall be

inspected for wear and tear and rejected, if worn. Check shall be done to

ensure that the moving parts of the sampler function freely before the

sampler is lowered into the borehole. While pushing the system into the

soil and till the beginning of the sampling operations, the bottom of the

piston shall be flushed with the cutting edge of the sampler. At the depth

of sampling, the piston should be fixed relative to the ground and the

sampler cylinder shall be independently pressed down smoothly and

continuously into the ground. If an obstruction is met with, the sampler

shall be withdrawn and another sample be taken after the obstruction is

removed. Accurate measurements of the depth of sampling, height of

sampler, stroke and length of sample recovery shall be noted and

recorded. After the sampler is pushed to the required depth, both the

sampler cylinder and the piston system shall be drawn up together

ensuring that there shall not be any disturbance to the sample which shall

ground water table in bore holes as per 1S:6935 and as per the

instructions of the engineer-in-charge.

a) In permeable soils, the water level in borehole shall be allowed to

stabilize after lowering it adequately by bailing. When water level inside

the borehole is found to be stable, the depth of water level below ground

level shall be measured. Stability of sides and bottom of the borehole

shall be ensured at all times.

b) For both permeable and impermeable soils, the following method

shall be suitable. The borehole shall be filled with water and then bailed

out to various depths. Observation on the rise or fall of water level shall

be made at each depth. The level at which neither a fall nor a rise is

observed shall be considered as the water table elevation. This shall be

established by three successive readings of water level taken at an

interval of two hours.

7.4.2 In case any variation in the ground water level is observed in any specific

borehole, then the water level in these bore holes shall be recorded

daily during the course of field investigation. Levels in nearby wells,

streams etc., if any, shall also be noted whenever these readings are

taken. If so called for, observation wells shall be drilled for the purpose

of long term studies on the fluctuation in ground water levels and

pressure. Either stand pipe or piezometer shall be installed at the

specified depths in the selected previously drilled bore holes or

specially drilled bore holes for this purpose as per the specification and
