| 摘要： | The Office of Geotechnical Engineering (OGE) of the Ohio Department of Transportation (ODOT) recognizes the need to develop a strategy to provide timely preventive maintenance to avoid on-set of large or catastrophic slope failures. Furthermore, with limited financial resources, the OGE is forced to make rational decisions on the priority of various landslide (slope failure) maintenance and remediation needs. To address these issues, this research project was undertaken with the following objectives: (a) Develop a field validated landslide geological hazard rating matrix, (b) Develop field reconnaissance forms in paper format and electronic format (window plus ArcPad), (c) Develop and deploy a web enabled, GIS based landslide database, and (d) Develop a users manual and training materials for the landslide geological hazard database. Based on synthesis of literature review of existing practices, ODOT in-house expert opinions, and knowledge of prevalent Ohio geological formations in landslide prone areas, the principal investigator developed the ODOT specific landslide hazard rating system, together with the field site reconnaissance form. A pilot database containing 39 landslide sites was compiled and statistically analyzed to ascertain the reasonableness of the hazard rating outcome. A web accessible landslide database in a GIS platform was developed, pilot tested, and deployed. / Supplementary Notes: Sponsored by Ohio Dept. of Transportation, Columbus. and Federal Highway Administration, Columbus, OH.
