Quasi Constant Value for Piles in Sands Solution

STEP 0: Pre-Calculation Summary

Formula Used

Quasi Constant Value = 0.5*Bearing Capacity Factor*tan(Angle of Internal Friction of Soil)
q_l = 0.5*N_q*tan(Φ_i)
This formula uses 1 Functions, 3 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)

Variables Used

Quasi Constant Value - Quasi Constant Value reached after penetrations of the bearing stratum in the range of 10 to 20 pile diameters.
Bearing Capacity Factor - Bearing Capacity Factor used in a bearing capacity equation that correlates with the angle of internal friction of soil.
Angle of Internal Friction of Soil - (Measured in Radian) - Angle of Internal Friction of Soil is a shear strength parameter of soils.

STEP 1: Convert Input(s) to Base Unit

Bearing Capacity Factor: 3.01 --> No Conversion Required
Angle of Internal Friction of Soil: 82.87 Degree --> 1.44635435112743 Radian (Check conversion here)
