• Abstract:
  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 user’s 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. In ; addition, a user’s manual was developed to assist training of the future users of the system. The ; benefits from full implementation of the landslide database and landslide hazard rating matrix include: ; (a) elimination of excessive paper work, (b) near real-time monitoring and data management, (c) ; centralized information, (d) uniform data collection and reporting, (e) enhanced data sharing. ; Furthermore, the Ohio Department of Transportation can reap the benefits of cost saving due to early ; stage detection of landslide and taking pro-active remediation measures.
