Problem Statement: Calculate the factor of safety with respect to cohesion, when a new canal is excavated to a depth of 5 m below ground level, through a soil having following characteristics: c = 14 KN/m2, Φ = 150, e=0.8 and G=2.70. The slope of banks is 1 in 1. If it is suddenly and completely emptied (Sn= 0.122), in both cases.
Solution:
Given Data:
- Depth of excavation, h = 5 m
- Unit Cohesion, c = 14 KN/m2
- Angle of internal friction, Φ = 150
- Void ratio, e = 0.8
- Unit weight of soil, γ = 2.70 KN/m3
- Banks slope, 1:1
- Soil bearing capacity factor, N = 0.083 (when canal runs full)
- Soil bearing capacity factor, N = 0.122 (when canal is emptied suddenly and completely)
Calculation for Full Canal:
- Effective angle of shearing resistance, Φ' = Φ - (Φ/2)*e = 150 - (150/2)*0.8 = 75
- Unit weight of water, γw = 9.81 KN/m3
- Active earth pressure coefficient, Ka = (1 - sinΦ')/(1 + sinΦ') = (1 - sin75)/(1 + sin75) = 0.32
- Passive earth pressure coefficient, Kp = (1 + sinΦ')/(1 - sinΦ') = (1 + sin75)/(1 - sin75) = 2.80
- Unit weight of soil below canal, γ' = γ - γw = 2.70 - 9.81 = -7.11 KN/m3
- Active earth pressure, Pa = Ka*γ'*h^2 = 0.32*(-7.11)*5^2 = -56.88 KN/m
- Passive earth pressure, Pp = Kp*γ'*h^2 = 2.80*(-7.11)*5^2 = 393.96 KN/m
- Net upward pressure, P = γw*h = 9.81*5 = 49.05 KN/m
- Factor of safety against sliding, Fs = (P - Pa)/c = (49.05 - (-56.88))/14 = 7.34
Calculation for Empty Canal:
- Effective angle of shearing resistance, Φ' = Φ - (Φ/2)*e = 150 - (150/2)*0.8 = 75
- Unit weight
