INTRODUCTION: DEEPEX – SHORING DESIGN SOFTWARE
DeepEX is a powerful software program for the design and evaluation of earth retaining systems. It can perform full structural and geotechnical design of any common wall type and support system.

E. DEEPEX – CONSTRUCTION STAGES (2D SECTION)
In DeepEX, we can generate and analyze all construction stages. This allows the advanced analysis methods (Non-Linear and FEM) to converge, as well as, allows us to review all results in all stages, recognize the most critical stage and take important decisions, in order to perform the most efficient model optimization. The model in this example (all construction stages) was created automatically with the DeepEX model wizard.
