Coefficient of Active Pressure given Total Thrust from Soil for Level Surface Solution

STEP 0: Pre-Calculation Summary

Formula Used

Coefficient of Active Pressure = (2*Total Thrust of Soil)/(Unit Weight of Soil*(Total Height of Wall)^2)
K_A = (2*P)/(γ*(h_w)^2)
This formula uses 4 Variables

Variables Used

Coefficient of Active Pressure - Coefficient of Active Pressure is the ratio of horizontal and vertical principal effective stresses when a retaining wall moves away (by a small amount) from the retained soil.
Total Thrust of Soil - (Measured in Newton per Meter) - Total Thrust of Soil is the force acting on unit length of soil.
Unit Weight of Soil - (Measured in Newton per Cubic Meter) - Unit Weight of Soil mass is the ratio of the total weight of soil to the total volume of soil.
Total Height of Wall - (Measured in Meter) - Total height of wall which is under the consideration.

STEP 1: Convert Input(s) to Base Unit

Total Thrust of Soil: 10 Kilonewton per Meter --> 10000 Newton per Meter (Check conversion here)
Unit Weight of Soil: 18 Kilonewton per Cubic Meter --> 18000 Newton per Cubic Meter (Check conversion here)
Total Height of Wall: 3.1 Meter --> 3.1 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_A = (2*P)/(γ*(h_w)^2) --> (2*10000)/(18000*(3.1)^2)

Evaluating ... ...

K_A = 0.115620302925194

STEP 3: Convert Result to Output's Unit

0.115620302925194 --> No Conversion Required

FINAL ANSWER

0.115620302925194 ≈ 0.11562 <-- Coefficient of Active Pressure
