Geological Information System (GIS) is a technique which can make geotechnical investigation easy for engineering purpose. It helps the engineer to analyze the ground data before physical inspection of the site. The area of research is the Nagpur district of Maharashtra, India. The topographic sheet for Nagpur is 55K/16 and 55O/4 of 2010. The Major purpose of this research was to determine the bearing capacity map, Contour map, and total land cover/land use map for a different purpose. From the above map, it will be easier for engineers to decide the type of Foundation and the trend of development across the city. Earlier, there was no method to store bore log and soil data to the exact location of the borehole, but today with the help of the Geospatial technique, researchers can assign soil data with every borehole. Nowadays, urbanization is speedily taking place due to which proper utilization is necessary for land according to its strength and properties. In this research, the author wants to collect different satellite imageries of Nagpur city and bore logs comprising of geotechnical data. The predicted outcome should show the contour map, elevation map, changes in land use pattern, and bearing capacity across the city. These help the researcher and engineers who are working in the same area for future site selection.

Geological Information System (GIS) is a tool which is used in different Areas to subside the human effort. The GIS was earlier developed to maintain the geological data of earth, but during the time GIS is used in different areas for research. The purpose of the study is to utilize GIS technique in the field of geotechnical engineering in different work like preliminary survey, availability of digitize Soil data of location, topographic survey. Due to availability of GIS, data can easily digitize according to the geographical coordinates. The satellite imageries of Nagpur city are collected from Earth Explorer a digital platform for researchers to access the satellite images of any Location. This satellite images are Landsat 7 ETM+, these images are later used to form composite image to develop Landuse Landcover map.

This study was conducted to have a detailed analysis of the geotechnical properties of expansive soil and fly ash from Sipat thermal power plant. It reported the findings of laboratory studies on certain common physical and geotechnical properties. The chemical properties and morphology of the black cotton soil (BCS) and fly ash is also determined using scanning electron microscopy and X-ray diffraction test. The geotechnical test includes determining specific gravity, particle size distribution, moisture content, standard proctor test, free swell index, and Atterberg’s limit. The different compositions of expansive soil with fly ash, yellow soil, moorum, and sand are studied. BCS was evaluated with fly ash, fly ash and sand, BCS with yellow soil, and moorum and fly ash. The study also analyzed the details and results of different tests conducted on soil samples. The results showed that strength and fly ash are inversely proportional; as fly ash increases, strength decreases, and vice versa. Fly ash was added from 20 to 80 % by replacing expansive soil by weight. The results indicated that expansive soil can be stabilized by the addition of fly ash to a limit of 10 to 20 %. HIGHLIGHTS The XRD And SEM results shows the mineral present in the FlyAsh and Expansive soil The geotechnical properties of Flyash and expansive soil is determined The OMC increases with decrease in densities The Particle size distribution curve shows the soil is GW soil GRAPHICAL ABSTRACT
