wherever required. All boreholes shall be sunk to the depths as specified in the

document.

5.2.3 Standard Penetration Test

In-situ field-test such as Standard Penetration Tests shall begin at a depth of

borehole 1.5 m. Thereafter, SPT shall generally be conducted in boreholes at

interval of 1.5 m. The tests shall be conducted as per IS-2131. For conducting the

test, the bottom of the borehole shall properly cleaned and split spoon sampler

shall be properly seated in position in the borehole. During cleaning of borehole,

additional measures as prescribed in IS 2131-1981 shall be considered like the

distance between end of casing and bottom of borehole should not exceed by 150

mm (if water is only used) and this distance can be extended upto 300 mm if

bentonite is used. While boring below water table, the water in the borehole shall

be maintained at least 1.5 m above the level of the water table. If cohesive soil

strata encountered, the borehole may be cleaned with bailer with a flap valve.

The test is basically a penetration test in which, a thick wall split tube sampler,

shall be driven into the undisturbed soil at the bottom of the hole under the blows

of a 63.5 kg drive weight with 75 cm free fall. The sampler shall be first driven

through 15 cm as a seating drive. It shall be further driven through 30 cm in two

stages of 15 cm each or until 100 blows have been applied. The number of blows

required to drive the sampler in second and third stage for penetration of 15 cm

each (total 30 cm) beyond the seating drive shall be termed as “Penetration

resistance N”. The samples collected shall be used as disturbed soil samples for

laboratory testing. The split spoon sampler shall conform to IS 9640-1980.

In case the blow count of SPT in soil (including the number of blows for seating)

exceeds 100, the corresponding penetration shall be recorded and this particular

test at that depth stopped. If the total penetration is more than the seating

penetration of 15 cm, then breakup of blow count for 15 cm seating penetration

and for remaining portion of penetration shall be reported.

5.3.4 Undisturbed Soil Samples

Generally, unless specified undisturbed soil samples (UDS) shall be obtained at

every 3.0 m interval starting from 3.0 m in all type of soil along the bore depth

upto SPT ‘N’ Values of less than 50. Sampler shall be 100 mm internal diameter and

soon as possible after the clean-out operation. Area ratio of the sample must

restrict to 20% for stiff formations & 10% or less for soft sensitive clays as per IS

1892-1979. However, area ratio is restricted to within 10% for thin-walled sampling



tubes because of the cutting shoes specifically designed in such a way that the area

ratio of within 10% can be achievable.

The cutting edge of the sampler shall be tapered at an angle 15⁰ ± 3⁰ degrees. The

sample tube / edge shall be free from rust, pitting, burring or any other defect.

The use of oil inside the sampler shall be limited to the minimum practicable.

5.2.5 Disturbed Soil Samples

In all boreholes, if undisturbed samples could not be collected due to reasons

stated above or if having non-plastic (cohesion-less) soil which could not be

extracted undisturbed, disturbed soil samples shall be taken at every 1.5 m

interval and at significant change of stratum. Soil from split spoon sampler used for

standard penetration tests shall be taken as disturbed samples. These samples shall

be placed without delay in polyethylene bags adequately sealed.

5.2.6 Drilling in Rock

Drilling in rock stratum shall be carried out using Nx size Bit and Double Tube core

barrel.

Core drilling shall normally be carried out with bits which shall be suitable for the

percentage core recovery and diameter required.

Rotary core drilling shall produce circular cores of a minimum 54 mm diameter

throughout the core length. The type and state of the drill bit, feed rates and

management of the drill shall be such that at least 95% core recovery in any single

run can be obtained.

obtained and the core barrel shall be removed from the drill holes as often as may

be required in order to get the best possible core recovery.

Rock cores recovered during drilling shall be arranged sequentially in core boxes

and shall be duly identified. Their Core Recovery (CR) and Rock Quality Designation

(RQD) shall be recorded in the bore-logs. The rock type shall be identified and the

core boxes and the identifications – Borehole number and piece number shall be

painted on them.

be correctly recognized as coming from a specified boring.

5.5 Handling of Samples

5.5.1 Disturbed Samples of Soil

Where samples are required for testing, or where it is desirable to keep them in

good condition over long periods, they should be treated as follows:

Immediately after being taken from the borehole or trial pit, the sample shall be

placed in a polyethylene bag. The bag shall be numbered and a label shall be

placed immediately. The bag shall be carefully packed in a stout wooden box

(preferably with separate partitions) with saw dust or other suitable material, to

prevent damage during transit. Where necessary, the samples shall be tested for

natural water content immediately on arrival at the laboratory and an accurate

description made of the sample. In such a case proper precautions shall be taken to

preserve the natural water content during sampling.

5.5.2 Undisturbed Samples of Soil

The following conditions of handling and protection of undisturbed samples are to

be regarded as a minimum requirement for samples taken by the usual methods; in

special cases it may be necessary to take more elaborate precautions:

Samples which are retained in a liner or which are retained in a seamless tube

sampler shall receive the following treatment: Immediately after being taken from

the boring or trial pit, the ends of the sample shall be cut and removed to a depth

of about 2.5 cm (or more in the top to cover any obviously disturbed soil). Several

layers of molten wax shall then be applied to each end to give a plug about 2.5 cm

thick. If the sample is very porous, a layer of waxed paper shall first be placed over

the ends of the sample. Any space left between the end of the liner or tube and

the top of the wax shall be tightly packed with saw dust or other suitable material;

and a close-fitting lid or screwed cap be placed on each end of the tube or liner.

The lids shall, if necessary, be held in position by adhesive tape. If the longitudinal

joint of the liner is not air-tight, this shall be waxed and protected by adhesive

tape in the same way as the lid.

A label bearing the number of the sample shall be placed inside the container just

under the lid. It shall be placed at the top of the sample. In addition, the number

of the sample shall be painted on the outside of the container, and the top or

bottom of the sample shall be indicated.

5.5.3 Samples of Rock

The reference number of the sample shall be recorded on it by painting directly on

the surface of the specimen. Samples shall then be packed in a wooden box. The

box shall be of such depth and the compartments of such width that there can be



no movement of the cores when the box is closed. The lid of the box shall be

adequately secured.

For determination Plastic Limit about 25 gms of oven dried sample (passing 400 μ

sieve) shall be taken and thoroughly mixed with water. The soil shall be rolled

between hand and glass plate so as to form a thread of 3 mm diameter. The soil

shall be kneaded and rolled again so that the moisture shall be gradually reduced.
