Abstract
The geological and geotechnical information for maintenance of slopes around existing structures is usually managed by individual branch in charge of the structure. Unitary management of the information is important for rational maintenance. Then we developed a computational slope maintenance system to deal with both geological and geotechnical information based on geographical information system (GIS). Following tools were programmed to estimate geotechnical information on GIS: (1) database-system of geological and geotechnical information, (2) total behaviors estimation tool for slope displacement data and (3) slope stability evaluation tool. The function of each tool was verified by applying pre-existing study of slope stability. This verification shows an example for practical use of the system. This unitary system could be efficiently used for maintenance works.
