Moment Reduction For Anchored Sheet Pile Walls

The design of anchored sheet pile by the free-earth method is based on the assumption that the piling is perfectly rigid and the earth pressure distribution is hydrostatic, obeying classical earth pressure theory. In reality, the sheet pile is rather flexible and the earth pressure differs considerably from the hydrostatic distribution.

As such the bending moments M(max) calculated by the lateral earth pressure theories are higher than the actual values. Rowe (1952) suggested a procedure to reduce the calculated moments obtained by the/ree earth support method.

Anchored Piling in Granular Soils
Rowe (1952) analyzed sheet pile in granular soils and stated that the following significant factors are required to be taken in the design

1. The relative density of the soil
2. The relative flexibility of the piling which is expressed as
