Geoinformation database system for the city of Astana

Abstract

This paper introduces the geoinformation database system for Astana city. Since the introduction of GIS-technology in the urban planning of the earlier stages allows to lay a common information base, both for design and survey works, and to effectively manage the process in the construction of buildings and structures that will solve the problem of rapid qualitative assessment of the construction site and decrease expenses for carrying out surveys and design work. The database system stores and display all the information in the borehole log such as lithological description and other geotechnical information. More than 2000 borehole data, 402 points of static penetration and 125 points of dynamic penetration were collected. Basically, the information including soil classification, location, depth and coordinates of boreholes, NSPT and NDPT values, and groundwater levels has been entered in the geo-database. By using the geo-database, cross-sections of an area can be easily drawn over the computer screen, and soil parameters such as soil classification, the thickness of each ground stratum, groundwater level, NSPT values, etc. can also be readily known.
