I’ll be brief since I have already mentioned this in a previous post and in the July GeoPrac newsletter. But today was the 40th Anniversary of the first time humans set foot on the moon. I’m embarrassed to say, but I mistakenly noted this historic anniversary as the 20th instead of the 40th anniversary in both of the above links. I’m surprised nobody called me on this, but I guess you ridiculed me in private. If you haven’t already, check out the wonderful article by Ed Nowatzki on the geotechnical engineering aspects of the lunar lander…fascinating reading, even for non-geotech types.
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.
