• Abstract:
  As part of the Ohio Department of Transportation’s (ODOT’s) ongoing effort to solve engineering problems for the Ohio ; transportation system through research, The Ohio State University has undertaken a study entitled “Bioengineering for ; Land Stabilization” under the direction of Professor Patrick J. Fox and Professor Emeritus T. H. Wu. ; A large number ; of slopes and embankments throughout Ohio are experiencing shallow slope failures and/or erosion problems. The aim ; of this study is to identify bioengineering methods to address ODOT’s slope stabilization needs in response to these ; occurrences. Bioengineering is an ecologically, and often economically, attractive alternative to conventional slope ; stabilization techniques. The objectives of this research are: 1) to identify important factors that control success or failure ; of bioengineering methods, 2) to develop installation techniques and designs for successful application of bioengineering ; methods, and 3) to provide thorough documentation to aid in the development of future design guides for bioengineering ; work for ODOT. ; Three field ; installations were conducted and monitored at demonstration sites located in Muskingum, Logan and Union Counties. ; Results indicate that biostabilization methods can be effective for the stabilization of shallow (less than 3 – 4 ft.) slides if ; vegetation can be established. Establishment of vegetation is dependent on local soil and climate conditions, especially ; during the first growing season after installation. The use of instrumentation (tensiometers, piezometers) can be effective ; in predicting vegetation survivability. Side-by-side panel comparisons indicated that varying installation techniques do not ; affect the survivability of live willow poles. The cost of bioengineering stabilization, if properly planned and implemented, ; is expected to be approximately 25% less than that of conventional methods.
