Intermediate values of earth pressure occur if the wall movement is insufficient to mobilize the active or passive limiting values. These values are of particular importance for designing embedded retaining walls, due to their flexible characteristics. The methods included in a standard are supposed to reflect the best (current) practice, however, the empirical methods included in EN1997-1:2004 and prEN1997-3:2022 are far from being considered reliable. Very recently, the author proposed a continuum mechanics approach for deriving earth pressure coefficients for any soil state between the at-rest state and the active or passive state, applicable to cohesive-frictional soils and both horizontal and vertical pseudo-static conditions. The same method also provides analytical expression for the calculation of the required wall movement (at any depth) for the mobilization of the active or passive failure state. In the present paper the author suggests a new, fully analytical method for designing embedded retaining walls, combining the aforementioned method with the well-known elastic beam theory. An application example is given indicating remarkable agreement with the finite element method, while when the proposed method is followed, more stable results are obtained.
