Geotechnical Assessment of the Site

The objectives of Geotechnical Survey were to assess soil profile of the site as well as

to find out electrical resistivity of the soil. Geotechnical investigation includes surface

& subsurface exploration, soil sampling, and laboratory analysis. Geotechnical

investigations have substantial importance in assessing requirement of foundation to be

laid down preventing human and material damage due to the earthquakes, foundation

cracks, and other catastrophes.

Soil resistivity is a measure of soil resistance to the flow of electricity. It is a critical

factor in design of the grounding system in an electrical substation, or for lightning

conductors. To attain the desired objectives, earlier there were 100 boreholes/trial

pits were drilled to assess the soil profile while 25 pits were drilled to assess electrical

resistivity of the soil. Subsequently, few more boreholes/trial pits were drilled to

assess the soil profile and electrical resistivity of the soil. In all, total of 142

boreholes/trial pits were drilled to assess the soil profile while 30 pits were drilled to

assess electrical resistivity of the soil. .

a. Borehole Investigation:

i) For geotechnical investigation work, auger boring used as per IS 1892-1979 clause

3.6.1.

ii) Drilling bore holes of size 100 mm/Nx size using auger boring up to refusal,

collecting necessary disturbed/undisturbed soil samples wherever strata changes.

iii) Standard penetration test was conducted in the bore holes at regular intervals of

1.5 m or at every change of strata, whichever is earlier as per IS 2131-1981.

iv) Disturbed and undisturbed samples were collected at different depths/wherever

strata changes as per IS 1892-1979.

v) Disturbed samples recovered were sealed in polythene labelled and sent to the

laboratory for laboratory test.

b. Standard Penetration Test:

Standard Penetration Test (SPT) was conducted as per IS: 2131 – 1981. SPT split spoon

sampler of standard dimensions was driven into the soil from the borehole bottom

using 63.5 kg hammer falling from 75 cm height. The SPT weight was mechanically

lifted to the specified height and allowed to fall freely on the anvil with the use of cat-

head winch with one to one and half turn of the drum. Blow counts for the penetration

of every 15 cm were recorded and the N is reported as the blow counts for 30 cm

penetration of the sampler leaving the first 15 cm penetration as seating drive.

When the number of blows exceeded 50 to penetrate the first or second 15 cm length

of the sampler, the SPT N is regarded as more than 100 as described in IS : 2131 - 1981.

The test is terminated in such case and a record of penetration of the sampler under

50 blows or more is made. SPT refusal is recorded when there is no penetration of the

sampler at any stage and also when a rebound of the sounding system is recorded. The

N values are appended in bore log sheet.

c. Trial Pits:

Fifty one Trial pits were excavated at various locations GPS coordinates as shown in the

coordinates tables Trial pits were excavated up to 4.0m depth from EGL. The soil

samples were collected and brought to laboratory for testing.

d. Laboratory Testing:

The following laboratory tests are carried out on soil samples collected at site as

applicable:

i) Grain size analysis

ii) Liquid limit, plastic limit and plasticity index

iii) Angle of repose and cohesion

iv) Sp. gravity

v) Bulk/dry density

vi) Natural moisture content

vii) Standard compaction test

viii) California bearing ratio (unsoaked & soaked)

ix) Chemical analysis of soil (PH, chloride, sulphate)

The test results of boreholes, trial pits, and chemical analysis of soil samples collected

at site are appended in below tables.

e. Findings of Soil Profile:

Soil properties in all 76 boreholes/trial pits is almost the same but in BH No. 1 to 5,

7,8,14,15,44,49 & 50 refusal strata met at 0.75 m depth and soil classified as sand with

gravel from EGL to 0.75 m depth. In this bore holes soil is non plastic and cohesion

less. In all bore holes % of silt & clay varied from 7 to 21 percent and gravels varied

from 13 to 29 percent and remaining part is sand. In BH No. 6, 9 to 13, 16 to 25, 29 to

31, 36, 38 to 41, 45 to 48 and 51 to 76 refusal strata met at 1.5 m, 3.0 m and 4.5 m

depth. Here Soil strata varied from medium to very dense 0.75 to 4.5 m. This soil is

also non plastic and cohesion less. In BH No. 26 to 28, 32 to 35, 37,42,43 soil strata

loose at 0.75 m medium from 1.5 to 3.0 m, dense at 4.5 m, and very dense below 4.5

m and BH no. 52 to 76 soil strata medium up to 1.5 m and dense below 1.5 to 4.5 m.

over all soil is classified in all Seventy six bore holes is sand. We have also conducted

Sixty six one trial pits from EGL to 3.0 m and one of trial pit is 4.0 m. soil strata of trial

pits is the same as bore holes and soil strata classified here also is sand. Some points

have been neglected because of transported dunes sand with height from 5 to 15 m.

Work could not be carried out there either by tripod or power shovel. Keeping this in

view, recommended safe bearing capacity as per shear criteria from 3.0 m to 6.0 m

depth as per IS 12070 with zero core recovery is 20 T/m².

6.0 62.16 63.39 20.00

Soil properties up to 6.0 m depth are almost same in all seventy six bore holes. Soil

containing 6 to 24 % clay and silt is classified as sand. Soil is non-plastic and cohesion

less up to 6.0 m depth in all fifty one bore holes. Rock was not encountered at

different level of depth in seventy six bore holes. Keeping this in view recommended

safe bearing capacity as per general shear criteria at 6.0 m depth as per IS 12070 with

zero core recovery is 20 T/m².

Soil strata were very hard so Excavation was not possible below 3.0 m by power shovel.

f. Electrical Resistivity Test:

Electrical resistivity test was conducted as per IS 7808: 1987 at thirty (30) locations by

Wenner four pin electrode configurations. The testing equipment passes a small, low

frequency AC current, of known value, through the ground via two current electrodes

(C1 and C2), and measures the potential difference between two additional voltage

electrodes (P1 and P2) at intermediate points.

The test is conducted by driving the four electrodes into the ground approximately

100mm to 200mm deep, in a line, such that the electrodes are symmetrical and equally

spaced. The soil resistivity measurements were recorded from the meter when the

readings stabilized in North-South direction and East-West direction. The depth of

influence on the test result was approximately 1/3 of the distance between C1 and C2.

Tests were conducted in two directions, and at different electrode spacing to provide

results applicable to a range of depths. This procedure may be standardized by taking a

set of reading at approximate pin spacing of 80, 165,320, 480 cm.

From the values obtained at field, the Qresistivity of the soil is calculated as follows:

Soil Resistivity (Ω) = 2π. A. R Where π = 3.142,

R = measured resistance between voltage electrodes, A = electrode spacing

meters.

Nokh Solar Park falls under Seismic Zone – III which is considered as moderate risk zone

(MSK scale VII). It simply means if earthquake occurs it will be of 5.0 - 5.9 magnitudes

on rector scale.

Water table at Nokh and neaby area is quite deep (more than 40 meters) and

underground water is available in limited quantity. The water available is saline which

is neither potable nor useful in module washing. Its extraction is not advisable since

the levels of the aquifers will be affected resulting in drying of the soil.

The site is least prone to any potential geological hazard like landslide, flooding &

erosion, subsidence, primary ground rupture, strong ground motion & liquefaction etc.

Bearing capacity of the soil is suggested as 20 T/m2. Foundations for PV mounting

structure will require depth of approx 5 – 6 feet.

The site has undulation. Earthwork will require for levelling the undulations which can

be done easily as the soil is sandy desert. This will be done by the Developers.
