effective stress in soil
For the given soil profile, Calculate the distribution of total stress, pore pressure, and effective stress along depth and report their values at point A, B, and C.
effective stress in soil
NOTE
Effective 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.
What is the pore water pressure?
Pore water pressure is the pressure of groundwater held between soil or rocks in the gaps (or ‘pores’) between particles. It is affected by the soil type, water flow conditions and level of the water table.
Total stress at a point is defined as the sum of the stress exerted by the total weight (solids plus water) of the soil/rock and the load on the foundation.
