Slope Acceptability
Slope Acceptability
(OP)
I've got an access road looping back on itself on a moderately sloped site.
There is a vertical separation between the two roads as they converge from 0 to about 8 feet maximum. I am able to maintain a consistent slope of 1:1.33 (V:H)across this vertical separation. I'm proposing a non structural concrete cap of 4-inches atop the slope to prevent erosion.
I am trying to save the cost of a retaining wall, however I've always kept 1:3 (V:H) as save rule of thumb for slope stability, and this is much steeper.
Both roadways will be installed in cut conditions up to 8-feet depth, and the geotechnical borings are 20-feet deep. The soil strata is primarily clayey sand.
The roadway load is expected to be light duty primarily, however must also be able to handle fire truck (H-20) loading.
Any suggestions on how to perform the stability analysis for this?

From here on, I will defer to him and others that have more direct experience with it than I do.
