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.
