Deep Excavation

"🏗️ Deep foundation design is rarely about checking just one pile or one loading condition. It’s about understanding the complete foundation system.

Different pile types, complex soil profiles, compression and uplift, lateral response, settlement, structural capacity, pile interaction, and soil–structure interaction can quickly turn foundation design into a fragmented workflow.

DeepFND brings these challenges together in one engineering environment. From individual helical piles, driven piles, and drilled shafts to pile groups, reinforced concrete pile caps, and pile rafts, engineers can analyze, compare, and optimize foundation solutions without moving between disconnected design tools.

🎥 In this video, see how DeepFND connects geotechnical and structural design—from conventional capacity calculations to nonlinear soil–pile interaction and finite element analysis—to help engineers develop safer, more practical, and more economical foundation solutions.

"🏗️ Complex geotechnical projects rarely have a single “right” analysis. The real challenge is understanding the problem from enough angles to make the right engineering decision.

Deep excavations, retaining systems, tunnels, waterfront structures, and urban infrastructure can involve everything from staged construction and groundwater to structural optimization and complex soil–structure interaction.

DeepEX brings these challenges into one connected engineering environment. Engineers can move from rapid model generation and traditional Limit Equilibrium analysis to nonlinear methods, FEM, structural design, optimization, and even 3D modeling—without losing continuity between the different stages of the design process.

🎥 In this video, discover how DeepEX helps engineers compare methodologies, investigate alternatives, understand complex behavior, and turn demanding geotechnical problems into practical and efficient designs.

Because better engineering isn’t just about getting an answer—it’s about having the tools to understand why.

"🏗️ How much does your excavation design depend on the analysis method you choose?

Limit equilibrium, nonlinear soil springs, and finite element analysis each rely on different assumptions and calculation procedures. Comparing their results can provide valuable insight into the behavior of an excavation support system and help engineers make more informed design decisions.

In this demonstration, we analyze the same 38-foot-deep braced excavation using all three methods within a single DeepEX project. We then compare the results, identify an overstressed structural member, and use DeepEX's automatic optimization tools to select a more suitable section before verifying the updated design.

In this video, you'll see how to:
✔ Analyze the same excavation using LEM, nonlinear soil springs, and FEM
✔ Compare critical results from different analysis approaches
✔ Review structural check ratios and detailed calculation reports
✔ Visualize FEM displacements, settlements, and support responses
✔ Automatically optimize an overstressed support member
✔ Reanalyze the model to verify the optimized design

DeepEX brings advanced analysis, structural verification, and automatic optimization together in a single engineering workflow—helping engineers design safer, more efficient, and code-compliant excavation support systems.

"🏗️ In finite element excavation analysis, the construction sequence is just as important as the final geometry.

A model may appear correct, but omitting intermediate excavation stages can significantly affect the calculated wall moments, displacements, support reactions, and ultimately the structural design.

In this video, we compare two identical DeepEX FEM models:
✔ One with the complete construction sequence
✔ One with several intermediate excavation stages intentionally omitted

By comparing the results, you'll see how construction staging influences the stress redistribution within the soil, the evolution of wall behavior, and the loads transferred to the support system.

In this demonstration, you'll learn how to:
✔ Build a staged FEM excavation model in DeepEX
✔ Compare complete and simplified construction sequences
✔ Evaluate differences in wall moments, shears, and displacements
✔ Review support reactions throughout construction
✔ Visualize soil displacements, settlements, and FEM contour plots
✔ Understand why proper staging leads to more realistic and reliable design results

Construction staging is not simply a modeling detail—it is a fundamental part of accurately simulating soil-structure interaction.

▶ Watch the video to see how omitted excavation stages can influence the results of a finite element analysis and why a properly staged model leads to more reliable excavation designs.

"🏗️ No two excavation projects are exactly alike—and neither are their retaining wall systems.

From soldier piles and sheet piles to secant piles, diaphragm walls, and combined retaining systems, engineers need the flexibility to model the solution that best fits each project's geotechnical conditions, construction sequence, and structural requirements.

In this video, we demonstrate how DeepEX makes it easy to create, edit, and manage wall sections while building realistic excavation models.

You'll see how to:
✔ Create and organize custom wall section libraries
✔ Select from a wide range of retaining wall types
✔ Define steel, concrete, and sheet pile wall properties
✔ Configure reinforcement for reinforced concrete walls
✔ Add and manage multiple main walls within the same model
✔ Adjust soil surfaces and groundwater levels for each wall
✔ Create wall elements to model variable wall sections and permanent basement walls

Whether you're designing a simple excavation or a complex multi-wall system, DeepEX provides the flexibility to model virtually any retaining wall configuration while integrating structural and geotechnical analysis in a single workflow.

"🌍 Reliable geotechnical analysis starts with reliable soil properties.

Whether you're designing deep excavations, retaining structures, or foundation systems, the quality of your results depends on how accurately the soil profile is defined. Combining engineering judgment with field investigation data is essential for developing realistic geotechnical models.

In this video, we demonstrate how DeepEX helps engineers define, estimate, and manage soil properties throughout the design process.

You'll see how to:
✔ Create and edit custom soil types
✔ Define drained and undrained soil behavior
✔ Configure advanced constitutive models for nonlinear analysis
✔ Estimate engineering soil properties from SPT data
✔ Perform statistical analysis and calibrate soil parameters
✔ Import CPT logs and automatically generate soil profiles
✔ Build more reliable geotechnical models using integrated estimation tools

By combining manual soil definition with SPT and CPT-based estimation methods, DeepEX helps engineers make the most of available site investigation data while improving the consistency and reliability of their analyses.

"🌍 Designing deep excavations often means complying with different structural and geotechnical standards, depending on the project location and client requirements.

DeepEX supports a wide range of international design codes for concrete, steel, and timber members, while also allowing engineers to apply geotechnical load combinations based on major international standards—or create fully customized combinations when project-specific requirements demand it.

In this short demonstration, you'll see how to:
✔ Assign structural design codes for all structural members
✔ Apply geotechnical load combinations based on international standards
✔ Automatically generate and compare multiple design combinations
✔ Review detailed structural calculations and code verification reports
✔ Create custom load combinations with user-defined partial safety factors

Whether you're designing according to Eurocodes, US, Canadian, Australian, or other international standards, DeepEX provides the flexibility to adapt your workflow while maintaining a consistent and efficient design process.
