Determines the slope stability using the planar failure analysis. 1 January 2016
FSplanar(c, phi, alpha, L, W, u)Factor of safety against shear failure on slopes with a planar failure surface
= soil cohesion [Soil parameters]
= soil friction angle [Soil parameters]
= angle of failure plane (degrees) [Slope geometry]
= length of failure plane [Slope geometry]
= weight of slope per unit width [Slope geometry]
= average pressure head on the failure plane [Slope geometry]
