WebEffective stress can be defined as the stress that keeps particles together. In soil, it is the combined effect of pore water pressure and total stress that keeps it together. It can also be defined in equation form as the total stress minus the pore pressure. WebTotal stress at a layer is the total weight present above the layer per unit surface area. Pore water pressure is the part of total stress resisted by water in voids. Effective stress is …
