Anyone have case histories for helical anchors used in California under seismic loading conditions (approx 10km from San Andreas Fault)? AB Chance website has one case, but it relies on the existing foundation for lateral resistance.
I am looking for references for geotextile reinforced slopes with cohesive backfill. I am aware that typically cohesionless soils are used for backfill, however, it is desireable to use the onsite cohesive soils if possible due to the large area.

Is it conservative/sufficient to multiply the rotational spring for an individual pile by the number of piles...
