Data visualization and use of statistics resulting into reliable databases could minimize uncertainty and optimize decision making in terms of both time and resources. Accordingly, this study presents a comprehensive geotechnical database of soil types found in Lahore division, which consists of four important districts of Punjab province, namely, Lahore, Sheikhupura, Kasur, and Nankana-Sahib. Data from 584 geotechnical investigation sites have been collected and analyzed that comprised of 433 sites for Lahore, 57 sites for Sheikhupura, 53 sites for Nankana Sahib, and 41 sites for Kasur District. The data is analyzed digitally and classification of areas into various zones based on standard penetration test results, which have been transformed into digitized geotechnical maps using ArcGIS package. To ensure repeatability and enhanced rigor, the data have been properly evaluated using methods of descriptive and inferential statistics to give the geotechnical designer a confidence to select appropriate SPT-N value while evaluating soil strength in a specific zone. The outcome of this study validated using tools of statistical analysis shall help practicing engineers to carry out prompt preliminary estimation of bearing capacity and other geotechnical parameters with reasonable reliability for foundation design considerations and planning the scope of geotechnical investigations for a site. The foundation design curves for both isolated and raft footings have been presented for the study area to demonstrate the practical utility of this study. [ABSTRACT FROM AUTHOR] |
