SnailPlus 2021 Slope Stability Analysis and Soil Nail Walls Design Software

SnailPlus is our soil nail analysis software. While soil nailing is also available in our DeepEX software program, SnailPlus was created to bring all the necessary capabilities into one package. SnailPlus 2021 is the latest version of our soil nail walls design software, following SnailPlus 2020, 2019, 2018 and 2017 versions.

WHY CHOOSE SNAILPLUS?

The software follows the FHWA methodology for the design of soil nail walls, in an interactive environment built on the DeepEX basic layout. This means that you can include all intermediate construction stages for your soil nail wall, include 3D loads, all in an interactive environment. Last, SnailPlus is the only software that produces a full printable report of all design calculations.

Who uses Snail-Plus?

Many companies including deparments of transportation such as Texas DOT, WASH-DOT, GZA, Hayward Baker, ESC Limited, D'Appolonia, Berkel Construction, and more!

Main Software Characteristics

 SLOPE STABILITY ANALYSIS AND SOIL NAILING METHODS

 

SnailPlus global stability of slope surfaces (simple or reinforced with soil nails).

SnailPlus 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. SnailPlus calculates the effects of the soil nails to the slope stability analysis.

 

  • Bishop Method
  • Morgenstern-Price Method (General Limit Equilibrium)
  • Spencer Method
  • French Clouterre standards for the soil nail design
 MULTIPLE SLOPE SURFACE SEARCH OPTIONS

 

SnailPlus can locate and report the most critical slope surface using various slope surface search methods:

 

  • Circular Slope Surfaces
  • Circular Surfaces with Active and/or Passive Wedges
  • Automatic Surface Search Method
  • Trilinear Surface Search Methods
  • Surfaces with Block-type failure
  • User-Defined Slope Surfaces
 FULL DESIGN OF THE SHOTCRETE FACING

 

SnailPlus can design the shotcrete facing. Two stage facings can be also defined and analyzed with the software.

SnailPlus performs checks on the soil nail head plates. 

 

  • Design of the shocrete facing
  • Two step facing available
  • Head plate checks
 MODEL WIZARD - CREATE A MODEL IN MINUTES

 

SnailPlus Model Wizard can be used to create any sloped surface with all construction stages, excavations and soil nail and facing installation in minutes. We can use the Wizard tabs to define all project parameters (sloped surface parameters, soil nail - head plates and shotcrete structural sections, stage options and design standards). The Wizard creates the model automatically, saving us a lot of time and effort for the initial creation. 

 SOIL PROPERTIES - SPT RECORDS - CPT LOGS

 

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

In SnailPlus we can create an unlimited list of soils and define all soil properties quickly. The software provides several estimation tools (SPT Estimator and partial estimation tools for each property using scientific methods and equations).

In SnailPlus we can add directly SPT Records and CPT Logs, which can be used from the software to estimate various soil properties.

  • Define list of soil types
  • Define list of stratigraphies (borings)
  • Soil properties estimation tools
  • SPT Records 
  • CPT Logs

 INTERACTIVE INTERFACE

 

SnailPlus is an extremely user-friendly software, which offers an interactive model interface. In the model area we can create all the stages stages and define all project parameters (external loads, soil nail sections, shotcrete section etc.) graphically.

All items on the model area (boring, soil nails, facing) can be accessed and their properties can be defined through user-friendly dialogs.

 DESIGN CODES AND SPECIFICATIONS

 

SnailPlus has implemented various different standards and specifications for the soil nails and shotcrete facing design.

In SnailPlus we can select ACI and FHWA specifications for the structural design. In the software we can either use Service Limit State or Ultimate Limit State methods.

 

  • ACI Direct method
  • FHWA and FHWA LRFD methods
  • LRFD WSDOT 2019 (GDM)
  • ASD Safety factors
  • LRFD FHWA GEC-7
  • EUROCODE 7 - ULS Approach
 EXPORT REPORTS IN PDF AND MS WORD

 

SnailPlus can generate extensive reports for all examined design sections and construction stages. The reports in SnailPlus are totally customizable - the end user can always select all the report sections included in the final report.

SnailPlus reports can include tables and graphs with all examined model properties and calculated results. We can also choose to include to the report all structural design equations and calculation procedure.

The SnaiPlus reports can be previewed, exported to PDF or exported to Word format, so they can be further edited by the user.

  • Select Design Sections to Report
  • Select Construction Stages to Report
  • Customize Report Graphs
  • Define Report Layout
  • Define Report Sections
  • Possibility to Report Equations and Stage Calculations
  • Preview the Report
  • Export Reports in PDF and Word Formats
