3. Use of MATLAB in identifying borehole log at a particular
location of a site
• To develop a mathematical model that could plot SPT profile & soil profile
at a particular alignment of a site.
• Predict borehole log at intermittent location using GPS coordinates or
Chainage location.
• To use predicted borehole log in case study of designing practical
problem.
• To validate the model using known soil profile data.
