摘要

Geotechnical properties are influenced by processes and conditions that vary in space and time, including erosion and deposition, stress history, depth to water, cementation, climate, and many other factors. Therefore the resulting properties of soil also vary in space. Inclusion of the spatial information associated with geotechnical data is essential for optimal use of such data. This paper describes how thousands of paper records of subgrade and pavement information were entered into a database adapted for storage of geotechnical information for the Kansas Department of Transportation. This information was georeferenced and imported into a geographic information system (GIS). This information is now available in an interactive system where it may be displayed, queried, or combined with other data for a wide range of analyses. A series of statistical analyses were conducted on the data. The resulting database has proven to be much more accessible than paper records and is capable of conveying a substantial amount of detailed information within the proper spatial context.
