Why Earth pressure at rest is used for basement slab wall, bridge abutment?
First of all you have to design that story building to provide reinforcement for all members such as slab ,beam,etc. by using different code such as IS etc.

If the wall is rigid and cannot be move when the pressure exerted on the wall, then the soil behind the wall is in the state of static equilibrium. This case is called rest earth pressure.
For bridges, slab walls and Abutments is soil mass or backfill with static equilibrium is required because it can bear the heavy load. Thus for safety point of view in construction pressure at rest is considered. In this case, all the pressures are being exerted uniformly on the retaining wall.
There are two types of conditions developed
For normally consolidated clay,
K= 1- sin(¢)
For overconsolidated clay
K(overconsolidated )= K(normally consolidated clay) x √OCR
OCR= OVERCONSOLIDATION RATIO
