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.

As soon as I hear anything about the new version and its additional features, I’ll be sure to post the info here. ReSSA is software for the design of reinforced soil slopes or RSS.
An update for the MSE wall design software MSEW was also released recently. This update is number 8.1 and primarily updates the way reinforcement database files are referenced, allowing the location of the database file currently in use to be stored in the project file. After recently completing a major MSE wall review using MSEW, all I can say is halleluia! I had to manually locate the database file for every single one of my old runs. This should be a nice fix.
ADAMA Software has released update 11 for their Mechanically Stabilized Earth retaining wall design software, MSEW 3.0 as of October 23, 2010. It appears that the changes mainly involve adding the updated AASHTO LRFD seismic […]
