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!
Most geotechs are familiar with the Journal of Geotechnical and Geoenvironmental Engineering (JGGE), one of the (if not the) premier journal in the industry. It’s published by the ASCE’s Geo-Institute (G-I) and accounts for about 20% of the revenue of the G-I organization.
The G-I’s President, Dr. Jean-Louis Briaud, convened a task force in early 2009 to investigate if the JGGE is “adequately serving as a venue for practice oriented papers.” According to the final report from the Proposed "Journal of Geotechnical Engineering Practice" Task Force, the reason for the task force is that:
