The method for retaining the excavated pit could have a significant effect on the soil pressure acting on the retaining walls; For this purpose, since the Top-Down construction method is widely used, In this study, a series of numerical analyses has been conducted to investigate the effect of the construction method on the soil pressure distribution. Generally, for engineering purposes, active and at-rest soil pressure distribution, as well as the Pack apparent pressure distribution are used for soil pressure determination. The results of the study suggest that in contrast to the at-rest and active soil pressure distribution, the pressure distribution on retaining walls has no similarity with the triangular distribution and the Pack's APD provides an acceptable estimation of soil pressure and its distribution. The results also show that with the increase of deformation due to the construction of the wall, the soil pressure acting on the walls is significantly reduced.
