Part of a parking lot on top of an MSE wall is settling, and a section of wall has failed by tipping
Part of a parking lot on top of an MSE wall is settling, and a section of wall has failed by tipping outward. Investigation revealed that the soil was compacted by running over it with a bulldozer, and density tests gave about 90% of the standard density. The builder claims that overloading at the surface caused the problem, and that the reduced weight of the soil should result in lower, not higher, pressures on the wall facing. (a) Is that a valid argument? Why (not)? (b) How will a lower compacted density influence wall pressure, sliding, overturning, and pull-out resistance? State your explanations in terms that can be understood by a jury. May 12 2022 05:57 PM
