Abstract:
Due to the escalating cost of site investigation in Australia, geotechnical data contributes substantially to the cost of engineering projects. The GIS (Geographic Information System) has been used as a vital tool in civil engineering in recent years for a variety of applications. The subsurface conditions of Surfers Paradise (as a case study) have been examined in terms of soil stiffness by using GIS. The Spatial Analyst extension in ArcMap10 has been employed to develop zonation maps for different depths in the study area. Each depth level has been interpolated as a surface to create zonation maps for the Standard Penetration Test SPT-N value of the soil for each depth. The Inverse Distance Weighting (IDW) method in the Spatial Analyst shows better representation for these zonation maps with certain parameters among 8 interpolation techniques.
