A Double Inequality Method for Calculate the Loading Capacity of a Sheet Pile DIMSP
The passive earth pressure on the both sides of a sheet pile retaining wall is owing to plasticity bounded, a fact that affects the horizontal loading capacity of the wall. In order to find out a method, that the loading capacity of the wall can be analytically calculated and the mentioned constrain could be token into account, the paper set up a DIMSP model, which consists of mechanics equilibrium principle including two inequalities for the plasticity condition of earth pressure. The deduced solution of the model is capable of calculating the bearing capacity, and possesses the advantages of no additional correction of the cut in depth of the wall. Further more the continuity of earth pressure distribution is ensured by this model, an adjustment of the earth pressure figure is also without difficulty possible. For engineering application some graphics are given, the cut in depth of the wall can be read from them conveniently.
