Notes on Pile foundations:
1. Ground level refers to MSL.
2. Groundwater level is generally at 0 – 2 m below the present GL.
3. Typical calculations for Pile capacities are given in Appendix – 2.
4. Lateral Pile capacity is taken as 15% of Vertical capacity.
5. All Piles considered to be of length 10 m, resting in gravel for 3 m depth.
6. (a) In BH-5 and BH-9, SDR is seen at a depth of 5 to 7 m.
(b) If SDR is reached earlier than 10 m, Piles may be rested in SDR strata, with an embedment of
1.5 m.
(c) Suggested minimum length of socket is as follows:
where D is the diameter of Pile. 7. All requirements of IS Code: 2911 shall be adhered to.
8. For other Pile Capacities, Pile dia / length may be modified.
Rock Type Embedment Length
Sound Rock 1 – 2 D
Moderately weathered rock 2 – 3 D
Soft Rock 3 – 4 D

Boundary wall foundations
Specific Recommendations for Boundary Wall Foundation:
The soils from 0 – 7 m are weak and soft soils (Clay /silty clay/silty sand). N values are less
than 10.
Considering the soft soils, the following alternatives are suggested:
Open foundations at a depth of 3 m with SBC of 10 t / sq m, and sand bed. SBC
calculations are given in Appendix – 1
Alternatively, 10 m long Piles may be used. Pile dia may be 300 mm with a vertical
pile capacity of 20 tonnes. Pile capacity calculations are given in Appendix-3.
PAVEMENT:
It should be noted that the top soil essentially consists of clay / silty clay / silty sand.
Thickness of this layer varies from 3.0 m to 9.5 m below existing ground level in
different boreholes.
Filled up soil of thickness 4.3 m exists in the area of Bore Hole-7.
Soaked CBR values of the top soil (clay/silty clay/silty sand) are quite low (3% to 4%).
Design:
As per Tender Document, Axle load transferred for each side of front axle of container
handling ‘Reach Stacker’ equipment is taken as 50 MT.
Sri Mohan Kumar, Manager, Railway Division, AARVEE Consultants, has given
Cumulative Standard Axles as 1.971 million times with full load over the surface.
From IRC: 37 – 2001 (Guidelines for Design of Flexible Pavments), Fig. 1 ( Pavement
design Thickness Chart ),
For CBR = 3 %, and Cumulative Standard Axles = 2 million,
Total Pavement Thickness T = 580 mm, say 600 mm
16
GEO TECHNOLOGIES
Balmer Lawrie & Co. Ltd.
Pavement design of Combination Block for 2 million Cumulative Standard Axles is as
follows (IRC: 37 - 2001):
Total Pavement Thickness T = Y + Z = 600 mm
Where Y = Thickness of Granular Base = 225 mm
Z = Thickness of Granular Sub Base = 375 mm
X = Thickness of Surfacing = 20 mm
17
GEO TECHNOLOGIES
Balmer Lawrie & Co. Ltd.
Base Material:
This requires the load spreading properties to reduce the stresses on the subgrade.
This has an important bearing on the performance of block pavement. Since the
available strata are unsuitable, base course should consist of unbound crushed rock,
water bound macadam, wet mix macadam, cement-bound crushed rock / granular
materials, and lean cement concrete.
In broad terms, whenever the subgrade is weak (with CBR < 5 %, as in the present
case), use of bound granular materials like cement treated crushed rock, requiring a
relatively thinner base, is recommended.
Sub - base Material:
The quality of sub-base materials includes natural gravels, cement treated gravels,
sand stabilized sub grade materials. The quality of sub grade materials should be in
conformance with IRC: 37 -2001 (Guidelines for the Design of Flexible Pavements).
Drainage:
Drainage of the pavement structural section improves its performance. Adequately
designed sub – surface drainage system consisting of an open graded drainage layer
with collector and outlet pipes should be provided (IRC: 37- 2001).

CHEMICAL PROPERTIES OF SOIL & WATER:
Results of Chemical analysis of soil are as follows:
Parameter Range Average
pH 7.76 – 8.02 7.9
Chlorides as Cl, ppm 420 – 445 433
Sulphates as SO4, ppm 282 – 201 242
Results of Chemical analysis of water are as follows:
Parameter Range Average
pH 6.23 – 7.15 6.7
Chlorides as Cl, mg/l 23100– 24400 23750
Sulphates as SO4, mg/l 4093 – 5068 4580
The values of Chlorides and Sulphates in water are in excess of permissible limits as
per IS: 456, and may have deleterious influence on concrete and steel. Effective
precautionary measures are required. Use of Sulphate-Resistant Cement and
Corrosion-Resistant Steel is recommended for sub-structure.

Note: Lab CBR values are generally less than Field CBR values since in field CBR test, a larger volume of soil, and hence more representative sample, is tested, and since the density of compacted CBR mould would generally be less than in-situ density as the in-situ soil is in confined condition unlike the laboratory mould.

APPENDIX-1: CALCULATION OF SAFE BEARING CAPACITY FOR OPEN FOUNDATIONS
a) Foundations resting in clay / silty clay at 2 m depth:
i)Shear Criterion :
Assumed depth of foundation D= 2 m
Assumed width of foundation B= 2 m
Unit wt of soil = 16.0 kN/cum Submerged unit wt r’= 6.2 kN/cu m
Cohesion c = 35 kN / sq m Angle of internal friction = 0 deg
Nc = 5.14 Nq =1.0 Nr = 0,0
Using IS Code: 6403-1981 formula :
Net ult BC = 1.3 cNc + r’ D ( Nq - 1) + 0.4 r’B Nr
= 234 kN/sq m
With a FS of 3.0, SBC = 78 kN/ sq m
Recommended SBC is 8 t / sq m, with sand bed.
ii)Settlement Criterion :
As per IS: 8009( Part 1)-1978
Settlement = [ p B ( 1- µ2 ) I ] / E
Where, p = Pressure, kN/ sq m = 78 kN/ sq m
µ = Poisson’s ratio = 0.5 E = Young’s Modulus = 5000 kN/sq m
I = Influence Factor =0.95
Substituting, Settlement = 22.5 mm < 40 mm (OK)
a) Foundations resting in clay / silty clay at 3 m depth:
i)Shear Criterion :
Assumed depth of foundation D= 3 m
Assumed width of foundation B= 2 m
Unit wt of soil = 16.0 kN/cum Submerged unit wt r’= 6.2 kN/cu m
Cohesion c = 45 kN / sq m Angle of internal friction = 0 deg
Nc = 5.14 Nq =1.0 Nr = 0,0
Using IS Code: 6403-1981 formula :
Net ult BC = 1.3 cNc + r’ D ( Nq - 1) + 0.4 r’B Nr
= 300 kN/sq m
With a FS of 3.0, SBC = 100 kN/ sq m
Recommended SBC is 10 t / sq m, with sand bed.
ii)Settlement Criterion :
As per IS: 8009( Part 1)-1978
Settlement =[ p B ( 1- µ2 ) I ] / E
Where, p = Pressure, kN/ sq m = 100 kN/ sq m
µ = Poisson’s ratio = 0.5 E = Young’s Modulus = 5000 kN/sq m
I = Influence Factor =0.95
Substituting, Settlement = 28.5 mm < 40 mm (OK)

b) Foundations resting in clay gravel / silty gravel at 3 m depth:
i)Shear Criterion :
Assumed depth of foundation D= 3 m
Assumed width of foundation B= 2 m
Unit wt of soil = 17.0 kN/cum Submerged unit wt r’= 7.2 kN/cu m
Cohesion c = 32 kN / sq m Angle of internal friction = 30 deg
Nc’= 16.17 Nq’ =7.36 Nr’ =6.64
Using IS Code: 6403-1981 formula :
Net ult BC = 1.3 c’Nc + r’ D ( Nq’ - 1) + 0.4 r’B Nr ‘
= 619 kN/sq m
With a FS of 3.0, SBC = 206 kN/ sq m
Recommended SBC is 20 t / sq m.
ii)Settlement Criterion :
As per IS: 8009 (Part 1)-1978 (Fig. 9)
For B= 2, N = 35
Settlement in m per unit pressure (kg/sq cm) =0.006
Settlement for Pressure of 200 kN/sq m (2 kg/sq cm) = 0,006 x 2 x 1000
=12 mm < 40 mm (OK)

APPENDIX-2: Typical Calculations for Pile Capacity
a) Cast in situ Bored RCC Piles : Pile Diamter D = 450 mm
Vertical Load:
Perimeter = P = 1.413 m C/S area A =.0.16 sq m
Length of pile L = 10 m, including 3 m embedment in gravel
Unit weight r = 16 kN/cu m Effective unit wt r’= 6.2 kN/ cum
End bearing :
Average angle of internal friction at pile tip φ = 40 deg ( for N = 50) IS :6403
Corresponding Nq value is 140 (IS: 2911 – 1982 )
Ultimate pile capacity in bearing :
Q b = A r’ L Nq = 0.16 x 6.2 x 10 x 140 = 1389 kN
Skin friction :
Neglect skin friction in clay/silty clay
For gravel :
Angle of wall friction = δ = 30 degrees (assumed)
Earth pressure coefficient K = 0.75 ( assumed )
fs= 0.5 x r’ x L x K x tan δ = 0.5 x 6.2 x 3 x 0.75 x 0.58 = 4 kN/ sq m
Qf = fs x P L = 4 x 1.413 x 3 = 17 kN
Pile capacity = Qb + Qf = 1389 + 17 = 1406 kN
With a FS of 2.5, Safe Pile capacity = 562 kN
Recommended vertical Pile capacity = 50 tonnes

Unit weight r = 16 kN/cu m Effective unit wt r’= 6.2 kN/ cum
End bearing :
Average angle of internal friction at pile tip φ = 40 deg ( for N = 50) IS :6403

For gravel :
Angle of wall friction = δ = 30 degrees (assumed)
Earth pressure coefficient K = 0.75 ( assumed )
fs= 0.5 x r’ x L x K x tan δ = 0.5 x 6.2 x 3 x 0.75 x 0.58 = 4 kN/ sq m
Qf = fs x P L = 4 x 1.884 x 3 = 22.6 kN
Pile capacity = Qb + Qf = 2430 + 22.6 = 2453 kN
With a FS of 2.5, Safe Pile capacity = 981 kN
Recommended vertical Pile capacity = 75 tonnes
