Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The actual problem for today is the introduction of geoinformation database in the management of urban planning. Development geoinformation database and using it in various civil engineering projects largely depends on the accuracy of available borehole information as well as borehole distribution density. The database development has focused in urban areas because of their social and economical importance. Geotechnical database plays a significant role to investigate the regional subsoil conditions prior to detailed investigation. The regional geotechnical characteristics can easily be grasped by the distribution of those soil properties. The Geo-database can provide sufficient and helpful information. This paper introduces the geoinformation database for Astana, but for the others areas efforts are underway. More than 2000 borehole data were collected. Basically, the information including soil classification, gradation, 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, gradation, the thickness of each ground stratum, map of zoning at optimization of length of driving and boring piles, groundwater level, NSPT values, etc. can also be readily known. The use was also made of the developed geo-database for assessing of the construction site and decrease expenses for carrying out surveys and design work. The given program, includes for today data of 2000 boreholes, 402 points of static penetration and 125 points of dynamic penetration which has allowed to analyse regional conditions of soils before detailed research.
