MULTIPLE ANALYSIS METHODS   

DeepEX implements all approved scientific methods for the design of deep excavation projects. With DeepEX we can select to perform the classical limit equilibrium analysis, we can use the non-linear analysis method with the use of elastoplastic Winkler springs (beam on elastoplastic foundations) or perform Finite Element Analysis.

Finite Element Analysis can be performed if you add and activate our Finite Element Analysis engine DeepFEM in any DeepEX version you choose.

   INTERACTIVE INTERFACE   

DeepEX is an extremely user-friendly software, which offers an interactive model interface. In the model area we can actually draw the model in each construction stage, by graphically adding loads and supports and by graphically performing excavations, backfill operations and dewatering.

All items on the model area (walls, supports, surface nodes, external loads) can be accessed with the use of the mouse and we can edit the properties of each item at any point through user-friendly dialogs.

The software provides tools for the quick model generation and surface modification.

   SOIL PROPERTIES - SPT RECORDS - CPT LOGS   

The soil types, soil properties and stratigraphies can be easily defined in DeepEX through user-friendly dialogs.

In DeepEX we can create an unlimited list of soils and define all soil properties quickly. The software provides several estimation tools (SPT Estimator and partial estimation tools for each property using scientific methods and equations).

The additional, optional module Soil Estimation Reporting and Statistical Analysis allows us to perform a statistical analysis of estimated soil parameters with a series of different methods. The statistical analysis allows us to estimate soil property variability with depth or in the project plan. Then, one can select the desired design values based on the desired confidence level.

In DeepEX we can add directly SPT Records and CPT Logs, which can be used from the software to estimate various soil properties

   DESIGN SECTIONS AND CONSTRUCTION STAGES   

In DeepEX we can create an unlimited number of design sections in the same software file, simulating all project walls. In each design sections, different soil parameters and stratigraphies, wall sections, support systems and design assumptions can be defined. 

In each design section we can create an unlimited number of construction stages, simulating the full design procedure. DeepEX presents extensive results for each stage, assisting with the identification of the most critical.

The use of the design sections and construction stages is important, since it can assist with the model optimization, leading to the most efficient solution.

   2D AND 3D DESIGN - CUSTOMIZABLE VERSIONS   

DeepEX offers a series of additional optional modules that can be used to totally customize any software version. 

DeepEX 2D can be used for the design and optimization of all project 2D design sections.

DeepEX 3D can also export the 3D Frame model with all bracing levels, so that the full project with all supports can be calculated. With DeepEX 3D we can also perform total cost estimation for the full project.

Additional modules can be added in any of the main DeepEX versions (2D and 3D), increasing the software capabilities:

• Export Drawings to DXF module can be used so all 2D sections for all construction stages and wall sections can be exported to DXF and opened in any CAD software. In DeepEX 3D, the same feature can be used for the export of the full project plan and side views.
• The Steel-Connection module allows us to easily generate all steel connections for walers to struts, and corner walers. Once a design is complete the steel connections can be optimized with a click of the button. The program will then automatically adjust weld sizes and apply plate stiffeners if required. Steel-connections can be evaluated with AISC 360-16 allowable or LRFD.
• The Export 3D Model Holograms module allows the export of the generated 3D Model holograms. The holograms are detailed models that can be opened either on the desktop or with Virtual or Augmented Reality Glasses, and they can be used to present the full model in great detail in real space. This way the user can both check any potential construction challenges (adjacent building foundations, underground utilities etc.), as well as, impress the clients with the view of the final project before it is constructed. The module allows importing 3D buildings back into the design environment.
• Our Finite Element Analysis engine, DeepFEM, can be added and activated in any software version, allowing the Finite Element Analysis method to be performed. The FEM method considers full soil structure interaction and can be used to analyze complicated models, adjacent foundation piles, tunnels and more.

   MODEL AND ANALYZE TUNNELS   

Model and analyze TBM, NATM or Box Tunnels with the Finite Element Analysis method (Prerequisites: FEM Module). Wizards give us the flexibility to easily create oval and complex tunnel geometries.

Sections and tunnel segments can be activated and deactivated at any stage. Soil losses and pressure grouting can also be modeled with ease.

   GRAVITY WALLS - PILE ABUTMENTS - SEA WALLS   

DeepEX allows the design of Gravity Retaining Walls, Pile Supported Abutments and Sea Walls with the corresponding additional, optional modules that can be activated inside the software. 

• Gravity Walls module: It allows the design of reinforced concrete gravity walls of any shape (Continuous walls or 3D Piers), calculating the wall sliding, bearing and overturning safety factors.
• Pile Supported Abutments module: It allows the use of foundation piles at gravity wall sections (creating pile supported abutments) and pile foundations adjacent to the excavation site. The module allows the calculation of the forces on each pile and the lateral and vertical design of the piles (calculation of pile moments, shear and displacements diagrams, as well as, the calculation of the bearing capacity of the piles).
  Prerequisites: Gravity wall module
• Sea Walls - Wave Pressures - Overtopping module: It allows the design of sea walls, block/segmental walls with individual shear resistances and densities, quay caisson walls (3D) with infill and more, the calculation of Wave pressures with Sainflou, McConnel, Proverbs, Load combinations for British Standards 6349 Parts 1-2 (Marine Structures-Quay Walls) and more.
  Prerequisites: Gravity wall module

   SLOPE STABILITY ANALYSIS AND SOIL NAILING   

DeepEX implements tools that can evaluate the global stability of excavation models and slope surfaces (simple or reinforced with soil nails).

DeepEX can calculate and report the most critical slope surface and the slope stability safety factor with the use of several scientific methods.

Soil nails can be used in the slope surfaces. DeepEX calculates the effects of the soil nails to the slope stability analysis.

• Bishop Method
• Morgenstern-Price Method (General Limit Equilibrium)
• Spencer Method
• Ordinary Swedish Method (method of slices)
• French Clouterre standards for the soil nail design

DeepEX reports can include tables and graphs with all examined model properties and calculated results. We can also choose to include to the report all structural design equations and calculation procedure.
