soil creep stabilization 2

[lem1]

Practical means for stabilizing existing slopes. Terracing, bulkheading, etc.?

 

[layfieldman]

What is the slope angle? Is it vegetated? What is the location? Obviously you don't want to excavate and build a MSE?

 

[GeoPaveTraffic]

There is no single way to stabilize all slopes. The appropriate stabilization method depends on the geometry of the slope, the reason for movement, and many other items specific to the particular problem.

If you can give us some specifics about the slope that is moving we can start giving some ideas.

I agree with the comments made by [blue]layfieldman[/blue] and [blue]GeoPaveTraffic[/blue]. We need site specifics in order to provide truly useful comments.

Why did you include the word "creep" in the title of your post?

PUt another hat in the ring for more info. Details of geometry - both of the slope, and for some distance either side of crest and toe. Benching. Soils - layers?; groundwater levels.

Chuck Brawner once told me - controlling groundwater can increase your stability by 30%; geometry adjustments only by 10% or so. I've never tried to confirm precision of numbers, but groundwatercontrol is usually the "key".

Awaiting your details -

BigH, I agree that groundwater is usually the "trigger" that causes movement. However, it can be difficult to stop movement by only changing groundwater. The reason is that most groundwater modifications take time and during that drawdown period the slope will continue to move often causing significant damage.
