4 Best Free Geotechnical Software For Windows

Here is a list of best free geotechnical software for Windows. The geotechnical field is a part of the civil engineering that concerns with the behavior of earth materials like soil, rocks, etc. It is used in various types of on-ground and underground construction to estimate the behavior of surroundings and earth materials over a structure. In order to estimate and measure the different aspects of earth’s material over a structure or behavior of different types of structure itself, you need these free geotechnical software.

Using these geotechnical software, you can perform various types of analysis on materials and structures to find better solutions. In most software, you can manually draw structures, select different materials, set materials properties, etc., and then perform analysis. In some software, you can also import pre-built designs and quickly perform tasks like analysis, pre-processing, post-processing, etc. To manually draw structure designs, these software offer tools like beam, cable, strip, soil surface, etc. Apart from analysis, you can also perform various geotechnical calculations through these software. In the response of analysis and calculations, these software provide output graphs and values. In resultant graphs, you can view bearing strength of the structure, intensity of different forces over the structure, and other important results. These software also let you save the output in XLS, PDF, CSV, and more formats.

All of these software are developed for professionals, hence they are not that simple to operate especially for novice users. Thus, I recommend users to check out user manuals of these software before using them.

PSlope

PSlope is another free geotechnical software for Windows. As its name suggests, it is primarily used to analyze and solve problems related to slopes. In this software, you can either manually create slope designs or import slope designs in DXF file format. In order to draw a slope structure or design, this software offers various drawing tools. Apart from designing the slope, you can also define types of materials (soil, rock, etc.) present on slope, define the internal properties of materials, and perform some geotechnical calculations. After performing the analysis and calculations, you can save all the results in a DOC file.

Features of PSlope:

  • Draw: It is a menu that provides all necessary slope and structure making tools such as soil surface, soil layer, line loads, phreatic layer, add grid, tangent line, etc.
  • Utilities: Using it, you can easily move different elements of slope structure, draw axis, draw dimensions, and add text to your model.
  • Calculations: It allows you to perform various geotechnical slope calculations using methods such as compute by one point, compute by circle, compute by tangent to line, and compute by block line.
  • General: It is a menu that provides two important tools namely Calculation Parameters and Soil Material. Calculation parameters tool lets you select different methods of analysis and allows you to specify material parameters like cohesion, friction angle, seismic coefficient, etc. Soil Material tool allows you to set soil layer data like soil color, bulk unit weight, saturation gamma, etc.

Limitations:

This geotechnical software can only be used to analyze and solve slopes related problems.

Final Thoughts:

It is another really good geotechnical software if you need to analyze and find solutions to slope based structures.

SO-Foundation

SO-Foundation is yet another free geotechnical software for Windows. This geotechnical software is primarily used to calculate the bearing capacity of shallow columns. It is also quite good software to estimate the failure stress of columns so that you can create the correct column designs according to structure requirements. In order to calculate the shear failure of columns or foundations, it provides various methods namely Eurocode, Hansen, Meyerhof, Vesic, and Terzaghi.

To help you perform different tests and understand the meaning of obtained results, this software provides two handy manuals namely Scientific manual and Verification manual on its interface.

Features of SO-Foundation:

  • Layers: In this section, you need to define all the necessary values and parameters related to a column or foundation like Thickness, Bounds, γ, ϕ, Rigidity, Pressure, and more.
  • Pressure Isobars: According to column parameters, this feature generates a visual representation of pressure at different parts of the column and its surroundings.
  • Bearing capacity: It generates multiple graphs showing bearing capacity based on different algorithms like Eurocode, Hansen, Vesic, etc.
