Pore Pressure given Effective Stress on Slice Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Pore Pressure = (Total Normal Force/Length of Arc)-Effective Normal Stress
ΣU = (P/l)-σ^'
This formula uses 4 Variables

Variables Used

Total Pore Pressure - (Measured in Newton) - Total Pore Pressure is the total pressure of the fluid in the pore space of the rock, when it exceeds the hydrostatic pressure, over pressure situation occurs.
Total Normal Force - (Measured in Newton) - Total normal force acting at the base of the slice.
Length of Arc - (Measured in Meter) - Length of Arc of the slice taken into consideration.
Effective Normal Stress - (Measured in Pascal) - Effective Normal Stress is related to total stress and pore pressure.

STEP 1: Convert Input(s) to Base Unit

Total Normal Force: 150 Newton --> 150 Newton No Conversion Required
Length of Arc: 9.42 Meter --> 9.42 Meter No Conversion Required
Effective Normal Stress: 10 Pascal --> 10 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ΣU = (P/l)-σ^' --> (150/9.42)-10

Evaluating ... ...

ΣU = 5.92356687898089

STEP 3: Convert Result to Output's Unit

5.92356687898089 Newton --> No Conversion Required

FINAL ANSWER

5.92356687898089 ≈ 5.923567 Newton <-- Total Pore Pressure

Length of Arc of Slice given Effective Stress

Go Length of Arc = Total Normal Force/(Effective Normal Stress+Total Pore Pressure)

Effective Stress on Slice

Go Effective Normal Stress = (Total Normal Force/Length of Arc)-Total Pore Pressure

Normal Stress on Slice

Go Normal Stress in Pascal = Total Normal Force/Length of Arc

Length of Arc of Slice

Go Length of Arc = Total Normal Force/Normal Stress in Pascal

Pore Pressure given Effective Stress on Slice Formula

Total Pore Pressure = (Total Normal Force/Length of Arc)-Effective Normal Stress
