The Minnesota Department of Transportation has released a technical brief that determines effective methods for stabilizing damaged roadway slopes. These methods could be used for local non-geotechnical engineers (ie. maintenance personnel) to identify the type of slope failure and then select an appropriate repair method. In addition, the methods can help determine whether slope damage repair can be completed by local engineers or if outside help is needed. Certainly, as a geotechnical engineer, I think this approach makes me a little concerned. But I understand the financial and logistical constraints for smaller municipalities and rural communities. When in doubt, I hope they confer with a geotech!
One year ago in Logan, Utah, a landslide caused a portion of an irrigation canal to fail, resulting in a secondary mudslide. A mother and two children were killed in the slope failure. Portions of […]
GeoSlope International has a nice overview of the general limit equilibrium (GLE) method in their February 2007 newsletter available from their website. I personally always struggle to remember the difference between the various methods of […]
A new publication was released from the TRB’s NCHRP program on Geofoam Applications in Slope Stability Projects. TRB’s National Cooperative Highway Research Program (NCHRP) Research Results Digest 380: Guidelines for Geofoam Applications in Slope Stability […]
