I’ve been very impressed with the geotechnical group at the Ohio DOT. They seem to be on the cutting edge of using modern technology to manage their geotechnical data. A few years ago, I posted about a presentation that described efforts to create and implement a geotechnical data management program at ODOT. Thanks to a colleague of mine (Thanks Sanjay), I found some more recent presentations at the EarthSoft website describing the work for ODOT. EarthSoft is the maker of the Equis family of database products, which is the key component of ODOT’s system. I’m pleased to see that ODOT is also using gINT for boring log and fence diagram output from the Equis managed database. [Source: Earthsoft]

Side Hill Retaining Walls – Part 2
In this part 2 of 2, various types of retaining walls are examined as possible alternatives in a side-hill retaining wall situation. These include conventional wall types such as CIP walls, MSE walls, gravity walls and soldier pile walls and some less conventional approaches such as lighweight concrete fill, hybrid soil-nail and geofoam wall systems, ground improvement and micropile walls.
Part 1 of this Side Hill Retaining Wall article covered the definition, significance, problems and failure modes, investigation techniques, analysis, and construction considerations of side hill walls. A PDF version is now available for download as well. Click through for the article and the download link!
