Efficient Design and Optimization of Bin-Type Wall Systems
Bin-type wall systems are a reliable and cost-effective solution for excavation support, particularly when multiple tiebacks are required. However, their design can quickly become complex due to the interaction between construction stages, anchor configuration, and soil behavior.
With DeepEX, engineers can design and optimize tied bin-type wall systems through a clear and efficient workflow, combining advanced analysis capabilities with a user-friendly interface.
In practice, the entire process can be summarized in three key steps:
Create the excavation model with all construction stages
Define anchor locations and structural properties
Analyze results and optimize the system
The following sections demonstrate how these steps can be implemented in DeepEX to achieve a reliable and optimized design.

Step 1: Create the Model (All Construction Stages)
A well-defined construction sequence is essential for accurate excavation analysis.
In DeepEX, models can be created either graphically, by defining each stage step by step, or automatically using the Model Wizard, which generates a complete staged model in seconds.
The process typically begins from at-rest conditions, followed by sequential excavation and support installation stages. By simulating each step of the construction process, DeepEX provides results for every stage, allowing engineers to:
Identify the most critical stage
Evaluate wall and support performance throughout construction
Make informed design adjustments early
This staged approach ensures that the design is not based solely on the final configuration, but on the actual evolution of the system.

Step 2: Define the Tie Rod Elevations and Structural Sections
Tie Rod Elevation and Spacing
Tie rod configuration plays a critical role in the overall stability and efficiency of bin-type wall systems.
In DeepEX, anchor elevations and spacing can be easily defined and modified either directly on the model or through the Model Wizard interface. This flexibility allows rapid testing of alternative configurations to improve system performance.

Anchor Structural Definition
DeepEX provides a comprehensive environment for defining anchor structural properties.
Engineers can specify:
Anchor type (strands, hollow bars, solid rebars, etc.)
Number of elements
Material properties
Grouted zone diameter
A built-in database of predefined anchor sections allows quick setup, while custom sections can be defined for project-specific requirements.

Step 3: Review the Results and Optimize the Model
Once the model is defined, DeepEX offers multiple analysis methods, including:
Classical Limit Equilibrium (LEM)
Non-linear analysis with elastoplastic springs
Finite Element Method (FEM)
After analysis, results are presented clearly for each construction stage, including:
Wall moments and shear forces
Support reactions
Structural check ratios
Embedment safety factors
This comprehensive overview allows engineers to quickly identify governing conditions and assess the adequacy of the design.
Model optimization can then be performed:
Manually, by adjusting wall sections and anchor configurations
Automatically, using DeepEX optimization tools that suggest efficient structural solutions
This significantly reduces design time while improving confidence in the final solution.

Conclusion
Designing bin-type wall systems requires careful consideration of construction staging, soil interaction, and support configuration.
DeepEX provides a powerful and intuitive platform that enables engineers to move efficiently from model creation to analysis and optimization. By combining advanced analysis methods with a staged modeling approach, the software helps ensure both safety and cost-effectiveness in excavation design.
