Two modes have been identified in the earthquake induced damage to soil structures and foundations associated with excess pore water pressure rise in saturated sand.
The average consolidation degrees defined by excess pore water pressure and settlement respectively are different to some extent.
By a quantity of detailed numerical calculation and analysis, space-time distribution of effective stresses, deformation and evolution of excess pore water pressure are simulated.
Research on dissipation of excess pore water pressure in one-dimensional finite strain consolidation of soft clays
The strain excess pore water pressure is a response of the residual strain potential coupled with the skeleton of soil.
According to the theory of equivalent of seepage discharge to volume change, a simplified formula for consolidation is derived from the concept of average excess pore water pressure.
The excess pore water pressure at the interface of the pile and soil is discussed too.
The excess pore water pressure of saturated soft clay foundation caused by pile pushing is obvious.
