Landslide debris barrier design - frestanding timber wall
Landslide debris barrier design - frestanding timber wall
(OP)
We have considered a building platform near the base of a moderate to steep slope that has experienced past landslope instability. Soil instability is limited to silt/clay flows due to saturation.
Does anybody know of any literature with respect to determining landslide impact forces for a mobilised soilmass with respect to design of a freestanding timber wall built to take the impact of the slide and protect the structure directly downslope.
Also, does anybody know of any literature that considers how to derive the pressure applied to the wall with respect to its design under dynamic conditions.

What I am trying to determine is design of a wall at the base of a slope to collect debris that has mobilised from the top of the slope. I am tring to determine the force that would be applied to the wall at the moment of impact as it would not just be something as simple as F = M x A.
Normally, for a wall design we adopt Pa = Ka x Gamma x Height^2 x (pole spacing) to determine loads on each pole - with the load applied at H/3. Obviously all of this changes with the nature of the load being applied by a debris flow.

Slump volume is about 800 cubic metres (20 metres wide x 3 metres deep x 15 metres up slope), mobilised from say 30 to 50 metres upslope. We aren't talking massive volumes, just small scale landslips.
