How to derive the capacity of load-bearing piles?
Basic difference is retaining wall is designed to resist backfill earth pressure and breast wall is resist for natural earthen slope of hilly area In hill.

In hill. When road is construct, at that time we need to cut-off some portion of hill and basically we construct two wall one is breast wall which is on hill side of the road to give stability of hill slop and another one is retaining wall which is construct on valley side of road which wall have backfill pressure plus road pressure on backfill so we need to design retaining wall for that backfill & surcharge .
See figure for different between retaining wall and breast wall.

The ultimate load bearing capacity for cohesive soil can be define by following formula: Where, Qu = Ultimate load capacity, kN Ap = Cross-sectional area of pile tip, in m2 Nc = Bearing capacity factor, may be taken as 9 ci = Average cohesion for the ith layer, in kN/m2 Asi = Surface area of pile shRead more
The ultimate load bearing capacity for cohesive soil can be define by following formula:
Where,
Qu = Ultimate load capacity, kN
Ap = Cross-sectional area of pile tip, in m2
Nc = Bearing capacity factor, may be taken as 9
ci = Average cohesion for the ith layer, in kN/m2
Asi = Surface area of pile shaft in the ith layer, in m2
