WebJan 1, 2024 · Determine you phi' from your atterberg data and ignore c'. A 20 x 20m foundation on a clay layer with a phi' of 20 to 23 degrees, unit weight of 19kN/m3, and groundwater at 1m depth achieves an allowable bearing capacity of 130 to 205kPa. However I am probably being conservative with some assumptions (i.e groundwater). WebWe assumed that soils with a high sand content have much lower cohesive forces and a different pore-size distribution compared to other (fine grained) soils. Therefore, texture is a main factor determining aggregation, soil type, and cohesion. Under extreme vertical compression, cohesion behaves differently in silt and clay soils than in sandy ...
