What is SnailPlus?

SnailPlus is a slope stability analysis and soil nail wall design software developed by Deep Excavation. While soil nailing capabilities are also available in the company’s flagship DeepEX program, SnailPlus was created to consolidate all necessary soil nail design features into one dedicated, streamlined package.

The software follows FHWA design methodologies and provides an interactive environment built on the DeepEX basic layout. This means engineers can include all intermediate construction stages, apply 3D loads, and work within a fully interactive modeling space. SnailPlus is also the only software in its category that produces a full printable report of all design calculations.

Target users include geotechnical engineers, civil engineers, structural engineers, contractors, and engineering consultancies involved in retaining wall design, slope stabilization, and deep excavation projects.

Use Cases

Highway & Infrastructure Projects – Stabilize long slopes and embankments along highways and railways. Tiered soil nail walls designed with SnailPlus are commonly used in transportation corridors.

Urban Excavation – In crowded city environments where space is limited, SnailPlus helps design retaining walls for deep excavations adjacent to existing structures.

Hillside Developments – Support construction on steep hillsides for residential or commercial developments. The software’s ability to model tiered walls makes it ideal for challenging topography.

Tall Soil Nail Walls – SnailPlus has been used to design the tallest soil nail wall ever constructed in the U.S.A.—a 105-foot wall in San Diego.

Stepped Wall Systems – Design and analyze multiple-tiered soil nail walls with complex geometry, including load transfer between tiers.

Seismic Design – Evaluate soil nail wall performance under seismic conditions with specialized analysis options.

Who Should Use This Software

Beginners – The model wizard guides new users through the design process step-by-step, making it accessible even for those new to soil nail design. Training materials, video tutorials, and example projects are readily available.

Professionals – Experienced geotechnical and structural engineers will appreciate the advanced analysis methods, code compliance, and comprehensive reporting capabilities that streamline complex projects.

Agencies & Consultancies – Engineering firms handling multiple projects benefit from the software’s efficiency, consistency, and ability to produce professional reports for client submission.

Academic Institutions – Researchers and educators can leverage SnailPlus for teaching slope stability concepts and conducting geotechnical research.

When NOT to Use This Software

• Very Simple Projects – For basic, non-critical slopes with minimal reinforcement, simpler tools or manual calculations may suffice.

• Non-Soil Nail Retaining Structures – For purely gravity walls, cantilever walls, or systems not involving soil nails, other Deep Excavation products like DeepEX may be more appropriate.

• 3D Finite Element Analysis – SnailPlus primarily uses limit equilibrium methods. For projects requiring full 3D finite element or finite difference analysis, additional specialized software may be needed.

• Budget-Constrained Small Firms – While cost-effective, smaller firms with very limited budgets might consider open-source or more basic alternatives for occasional use.

SnailPlus vs Competitors

GEO5 Nailed Slope offers solid nailed slope analysis but lacks some of SnailPlus’s advanced features like prestressed nails and genetic algorithm search.

Talren is strong for general slope stability with reinforcements, but SnailPlus provides more specialized soil nail design capabilities and comprehensive reporting.
