When a holding wall moves laterally, the ground pressure decreases on the active side of the divider, and after the maximum friction force is mobilized at the base of the obstruction, the thrust increases on the passive side. The sideways displacement ends when the balance of forces in the level direction is attained. The theories of Coulomb and Rankine favor that the shear strength of the soil held by the obstruction is completely mobilized, but this theory is not fulfilled, because the wall stops when the balance of forces is attained in the horizontal direction, so the soil thrust acting on the alive side is greater than the alive thrust calculated accompanying Coulomb and Rankine theories, therefore, an mistake is incurred, namely on the side of danger. In this item based on Coulomb’s hypothesis a method is presented to reckon the earth thrust on the alive side of the wall taking everything in mind the safety determinants which the obstruction is designed. After the dust thrust on the active side is acquired, the earth thrust on the inactive side is obtained from the balance of forces in the level direction. A efficient example is presented, place the traditional methods is compared accompanying the one established here, place the differences are important, and they are in support insecurity. Accompanying the traditional methods the wall does not disconnect from the base, while with the individual exposed here the obstruction detaches from the base.
