   INTERACTIVE INTERFACE - EVEN TALK TO IT 

DeepEX offers an extremely user-friendly software with an interactive model interface. You can draw supports, loads, and items in the model area for each construction stage, and graphically perform excavations, backfill operations and dewatering.

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

Quickly generate models with a powerful wizard.

Last, you can talk to DeepEX and tell it to prepare a deep excavation model "Hey DeepEX.." "Create a 10 meter deep excavation with struts".

   SOIL PROPERTIES - SPT RECORDS - CPT LOGS   

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

Create an unlimited list of soil types and quickly define all soil properties. Quickly estimate soil properties with several estimation tools (SPT, CPT Estimator and other tools with industry accepted methods and estimation equations).

The additional, Soil Estimation Reporting and Statistical Analysis module, allows you perform a statistical analysis of estimated soil parameters with a wide range of 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   

All your design can be in a single file. You can create an unlimited number of design sections in the same file, simulating all project wall sections and different excavation depths. In each design sections, different soil parameters and stratigraphies, wall sections, support systems and design assumptions can be defined.

Create an unlimited number of construction stages, simulating the full design procedures or conditions in each design section. DeepEX presents extensive results for each stage, assisting with the identification of the most critical condition.

Easily examine alternatives within different design sections. This allows you to quickly identify the most critical or most efficient deep excavation solution.

   2D AND 3D DESIGN - CUSTOMIZABLE VERSIONS   

Meed additional design challenges with additional DeepEX modules. Not all deep excavations require the same capabilities. You can expand your solution capabilities with the following DeepEX versions/modules:

DeepEX 2D: For the design and optimization of all project 2D design sections.

DeepEX 3D: 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:  With this module 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.
• Steel-Connection module: Allows you 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.
• Export 3D Model & Holograms module:  This module allows your the export the deep excavation  model to a 3D desktop, virtual reality, or augmented reality (HoloLens) model. Easily visualize the 3D model excavation before it is constructed and communicate with your clients some of the complexities and construction staging. This way check for 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.
• Finite Element Analysis module: DeepFEM, can be added and activated with 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

   EXPORT REPORTS IN PDF AND MS WORD
