Mn/DOT’s ‘On-Line’Geo-Spatial Borehole/Sounding Database Development

摘要

Minnesota Department of Transportation (Mn/DOT) has advanced over 20,000 soil borings and CPT soundings in the past 46 years. An electronic database of point data was established in the 1970’s. A web-based interface and set of query tools was developed in 2003. An intranet version is being used; the public version is expected to be ready in fall of 2006. With minor changes to the data nomenclature, Mn/DOT’s system is expected to be fully compatible with evolving geotechnical management systems being developed by a number of cooperating international agencies. Development of the Mn/DOT system, obstacles, difficulties, and benefits are described.
