Apart from following general outlines for input procedures and parameter findings when performing excavationanalysis using FEM, some additional considerations should be taken. The influences of appropiate soil stiffness, pre-load efficiency, actual strut stiffness, soil/wall interface, crack in concrete retaining wall, and foundation piles installed before excavation have been investigated to weight the impact on analysis quality, enhancing acceptability in practice. Computed deformations and strut axial loads of a case study agreed quite well with field responses after applying these effects.
