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.
