Modelling rock in GEO5 Sheeting Check

Modelling rock in GEO5 Sheeting Check

RE: Modelling rock in GEO5 Sheeting Check

I'm not familiar with that program, but you could possibly model massive, competent rock as a clay with a very high cohesion. However, just because it is rock doesn't mean there isn't any lateral pressure. If the rock is very fractured or if the rock slopes downward toward the wall, there could be lateral pressure. Rarely do borings or a geotech report give any information about the bedding and joints in rock that will be excavated and possibly need support from sheeting or rock bolts.
