The calculation approach used is the limit equilibrium; the analysis can be conducted in both drained and undrained conditions. In both cases, for the calculation of the embedment depth of the wall, a simplified calculation scheme is considered, applying the moment equilibrium equation around the point where the active earth pressure is balanced by the passive earth resistance.
In anchored sheet pile walls, stability does not depend only on the development of passive resistances below their embedment line, but there is a collaboration of the forces mobilized by other elements completing the structure.
The main calculation schemes to analyze the equilibrium of an anchored sheet pile wall assume:
-
That the base of the sheet pile is free to rotate and that no passive resistance develops on the side where the sheet pile supports the soil;
-
That the base of the sheet pile cannot rotate.
The calculation schemes are known as:
a) free earth support method,
b) fixed earth support method.
