GeoSpring 1.0: A Software Tool for The Design of Shallow and Deep Foundations

September 2020
GeoSpring 1.0 Presentation / Wafi Bouassida 1
Software Development In Geotechnics: A balance between rapid computation and coherent results
• Massive Geotechnical Database allowed engineers and researchers to
develop convergence based Methods giving fast & high precision
results avoiding the use of FEM which can be awkward in Time
• For example: The settlement of single Piles and Piles Group using the load transfer method is more preferred to be used than FEM in both consulting reports and scientific papers
• These Methods can be combined with machine learning techniques to develop decision making algorithms in Foundation Design

GeoSpring 1.0: An Overview
• A Software Tool Designing Foundations for Structures
• Developed since 2015 and Validated by Wafi Bouassida
• Considered Now as a VP (Viable Product) and Ready to be marketed
• Can be Improved in The Future by adding it New ComputationalModules and greater Interface Lookings
• Target Clients : Technical Consulting Firms, Construction Companiesand Civil Engineering Schools

GeoSpring 1.0 : Growth Strategy Plan / Wafi Bouassida 5
Shallow Foundations Module
• Bearing Capacity according to EC7 (The Hansen’s Method)
• Short Term (EC7) / Pressuremeter and Oedometric Settlement (Single Footings & Footings Group)
• What’s new ?: Settlement Variation along the footing width to optimize in Steel Reinforcement
• 3D contours of footings group to visualize the interaction between these elements

Deep Foundations Module
• Bearing Capacity of single piles (C-Phi & Pressuremeter Methods)
• Settlement of Single Piles (Load Transfer Method : Cubic roots / Frank & Zhao)
• Settlement of Pile Groups (Load Interaction Factor Method & Equivalent Pier Method)

Embankments Modules
• Short Term & Long Term Settlement of Trapezoidal and Triangular Embankments
• What’s New ?: Settlement Variation along the embankment width
• This variation can be used to optimize the design of vertical drains or the reinforcement of Rigid Inclusions beneath embankments

Run GeoSpring /Pre-Design Of Rigid Inclusions
• Determine the needed IAR (%) to limit the settlement of compressible soils beneath the designed foundations
• What’s new ? : Obtain all the possible couples of IAR (%) and Target Settlements from a ”one-shot simulation”
• GeoSpring has been used in the Lake Bay Project : The most large scale Rigid Inclusions Project In Tunisian Capital
