Is force and moment equilibrium satisfied by Janbu’s method, Bishop’s method and Morgenstern-Price method?

Janbu’s method and Morgenstern-Price method are non-circular analytical method and they are frequently used for soil slopes while Bishop’s method is circular analytical method. Bishop’s Simplified method and Janbu’s Simplified method assume that the inter-slice forces are horizontal and inter-slice shear forces are neglected.


Equilibrium Method

Janbu’s Simplified No Yes Yes
Bishop’s Simplified Yes No Yes
Morgenstern-Price Yes Yes Yes

This question is taken from book named – A Self Learning Manual – Mastering Different Fields of Civil Engineering Works (VC-Q-A-Method) by Vincent T. H. CHU.
