Neutral Stress per unit area for Dams on Soft Foundations Solution

STEP 0: Pre-Calculation Summary

Formula Used

Neutral Stress = Depth of Dam*Specific Weight of Water in KN per cubic meter*(1+Height of Dam/Minimum Safe Length of Travel path)
σ_{Neutralstress} = D*W*(1+h/L_n)
This formula uses 5 Variables

Variables Used

Neutral Stress - (Measured in Pascal) - Neutral Stress in a soil mass is a force per effective area.stress taken up by the pore water and stress taken up by solid particles.
Depth of Dam - (Measured in Meter) - Depth of Dam is the distance from the top or surface to the bottom of something.
Specific Weight of Water in KN per cubic meter - (Measured in Newton per Cubic Meter) - Specific Weight of Water in KN per cubic meter is the weight per unit volume of water.
Height of Dam - (Measured in Meter) - Height of Dam is the distance between the lowest and highest points of a person/ shape/ object standing upright.
Minimum Safe Length of Travel path - (Measured in Meter) - Minimum Safe Length of Travel path is the measurement or extent of something from end to end.

STEP 1: Convert Input(s) to Base Unit

Depth of Dam: 3 Meter --> 3 Meter No Conversion Required
Specific Weight of Water in KN per cubic meter: 9.81 Kilonewton per Cubic Meter --> 9810 Newton per Cubic Meter (Check conversion here)
Height of Dam: 15.6 Meter --> 15.6 Meter No Conversion Required
Minimum Safe Length of Travel path: 2.9 Meter --> 2.9 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_{Neutralstress} = D*W*(1+h/L_n) --> 3*9810*(1+15.6/2.9)

Evaluating ... ...

σ_{Neutralstress} = 187743.103448276

STEP 3: Convert Result to Output's Unit

187743.103448276 Pascal -->187.743103448276 Kilonewton per Square Meter (Check conversion here)

FINAL ANSWER

187.743103448276 ≈ 187.7431 Kilonewton per Square Meter <-- Neutral Stress
