Deep Excavation

"🏗️ How much time do you spend just setting up excavation models before the real engineering even begins?

For many projects, model generation itself becomes a bottleneck.

👉 Defining stages manually
👉 Adjusting support elevations
👉 Assigning wall sections
👉 Configuring load combinations and groundwater conditions

…and repeating the process every time a design changes.

In this video, we show how the DeepEX Model Wizard can generate complete excavation models — including construction stages — in just minutes.

✔ Select the project type
✔ Define soils and stratigraphy
✔ Adjust walls and supports
✔ Apply surcharges and design codes
✔ Generate the full staged model automatically

Because faster model setup means engineers can spend more time evaluating behavior, optimizing designs, and reducing project risk.

What part of the excavation model setup usually takes the most time in your workflow?

"🌉 Are you analyzing your bridge abutments as simple retaining walls… while ignoring how the piles actually interact with the system?

Pile-supported abutments are not just walls with foundations.

👉 Backfill pressures
👉 Pile stiffness
👉 Groundwater conditions
👉 External surcharges
👉 Soil–pile interaction

…all influence the final behavior of the structure.

In this video, we show how to:
✔ Create a pile-supported abutment model in DeepEX
✔ Define pile layouts, geometry, and reinforcement
✔ Simulate staged backfilling and external loads
✔ And review wall and pile stresses, moments, shears, and displacements

Because understanding how the wall and piles work together can significantly improve both design efficiency and project reliability.

How detailed is your typical pile-supported abutment analysis workflow?

"How much time do yo lose, just trying to navigate complicated software interfaces?

This is something we focused on heavily in DeepEX.

Because excavation and tunneling projects are already complex enough:
👉 Multiple analysis methods
👉 Construction staging
👉 Structural checks
👉 FEM models
👉 Seismic and stability analysis

The software should help simplify the workflow — not slow it down.

In this video, we walk through the DeepEX interface and show how engineers can:
✔ Build excavation models graphically
✔ Define staging and supports efficiently
✔ Run LEM, Non-Linear, and FEM analysis
✔ Review structural checks and optimization tools
✔ And even work with full 3D excavation and tunnel models

Because better engineering decisions often start with a workflow that makes complex analysis easier to understand and manage.

What feature do you think saves engineers the most time in excavation software?

"Designing a Gravity Wall… but Missing the Full Stability Picture?

Many retaining wall designs look fine— until you check all failure modes together.

Sliding.
Overturning.
Bearing capacity.
Slope stability behind the wall.

And that’s where things often get overlooked.

In this video, I walk through how to model and analyze a gravity (inverted T) retaining wall in RetainEX, including:

✔ Full wall geometry definition
✔ Realistic soil stratigraphy
✔ External surcharge loading
✔ Staged construction
✔ Integrated slope stability analysis (GLE method)

We don’t just stop at pressures and moments.

We also check:
• Sliding, overturning & bearing safety
• Critical slope failure surface
• Global stability safety factor

Because a wall that works structurally… can still fail geotechnically.

Do you typically include slope stability in your retaining wall checks?

"Still Designing Complex Excavations in 2D? You Might Be Missing the Real Behavior.

Most excavation designs start in 2D.

But real projects rarely are.

Corners.
Irregular geometries.
Complex support layouts.

These introduce 3D effects that 2D sections simply can’t capture.

In this video, I show how DeepEX 3D extends the same DeepEX platform — it’s not a different program.

You still have everything from DeepEX 2D:
✔ 2D modeling
✔ LEM, nonlinear & 2D FEM analysis
✔ Tunnel design capabilities

And on top of that, you can:

✔ Model excavations of any shape in full 3D
✔ Analyze real load distribution on struts, tiebacks & walers
✔ Perform structural checks — including connections
✔ Evaluate impact on adjacent structures (settlements, damage, crack risk)

Plus:

🔹 Generate full 3D FEM models in seconds
🔹 Review soil stresses, displacements & system behavior in detail

Because in complex excavations,
what you don’t model… is often what governs the design.

At what point do you decide to move from 2D to 3D in your projects?

"Designing Helical / Displacement Piles? Are You Checking Everything That Matters?

Helical and drilled displacement piles are often chosen for efficiency.

But design isn’t always straightforward.

You need to evaluate:
• Compression and uplift capacity
• Installation torque
• Lateral performance
• Structural stresses
• Soil–pile interaction

And missing one of these… can lead to unsafe or overly conservative designs.

In this video, I walk through the full analysis of a Stelcor drilled-in-displacement pile in DeepFND:

✔ Real soil stratigraphy & spring properties
✔ Helical plate configuration & grouted section
✔ Multi-stage loading (compression, uplift & lateral)
✔ Axial + lateral analysis in one model

We review:
– Bearing capacity (tension & compression)
– Installation torque estimation
– P-Y curves & lateral response
– Structural check results for the pile and plates

Because modern pile design isn’t just about capacity —
it’s about understanding full behavior.

Do you typically check lateral response and torque when designing helical piles?

"Designing Next to Rail Loads? One Analysis Method Might Not Be Enough.

Excavations near train embankments are not forgiving.

You’re dealing with:
• Surcharge from moving loads
• Complex soil behavior
• Strict displacement limits
• High consequences if assumptions are wrong

So the question is:

👉 Can you trust a single analysis method?

In this video, I walk through a cantilever excavation next to a railway embankment in DeepEX, including:

✔ Realistic soil stratigraphy & hardening behavior
✔ Train load simulation with distributed pressures
✔ Staged excavation modeling
✔ Sheet pile wall design (AZ section)

Then I analyze the same model using:

• LEM (Limit Equilibrium)
• Nonlinear analysis
• Full FEM

And compare:
– Wall moments & shears
– Displacements
– Soil stresses & settlements
– Overall system behavior

The differences can be significant — especially under surcharge conditions like rail loads.

Choosing the right analysis approach isn’t just a technical detail.
It’s a risk decision.

Do you typically validate your excavation models with more than one method?
