Stability Analysis of Sheet Piles Applying the Principle of Least Work

Abstract

This paper shows that a stability analysis of anchored sheet piles may be done applying the principle of least work, when a suitable distribution pattern of earth pressure is assumed. An example is shown in Fig. 1.
aking use of this result, one can easily obtain the tension of an anchor rod, the depth of the buried portion of a sheet pile, and the maximum bending moment and the point it which it occurs when the angle of internal friction is decided, and also the appropriate location of the anchor rod.
Furthemore, the stability analysis of sheet piles without anchor rods for the same earth pressure distribution is shown.
