Geotechnical Geo-Information System of Astana

Abstract

The article considers the Geotechnical Geo-Information System (GGIS) of Astana, Kazakhstan. The GGIS was developed by methods of geoinformatics applied to engineering survey and geotechnical monitoring technologies. A special database program and set of geotechnical zoning maps were created for differentiation by ground bases type, showing the quaternary sediments and bedrock soils distribution, allowing for more efficient field investigations and engineering geological surveys, thus optimizing the length of piles foundations. The GGIS enables engineers to better justify the selection of particular designs, and significantly reduces the time and costs of field investigations and foundation design and construction.
