Abstract

A deeper inspection has been made into the physical meaning and mechanism of the soil liquefaction. Emphasis has been laid on the stress condition and stress evolution in saturated cohesionless soils during liquefaction. Typical examples have been described to demonstrate the process of stress evolution in soil liquefaction. Some other related factors such as limit equilibrium condition, strain and pore water pressure evolution in the saturated cohesionless soil mass under cyclic loading or vibration have also been discussed. It has been concluded that the state of stress in saturated cohesionless soils is bounded by limit equilibrium condition and approaches the "hydro-static pressure" in the course of liquefaction, the pore water pressure evolution during soil liquefaction can be correlated with the fabric characteristics and drainage condition of the soil mass, and the strain does not seem to be a proper reference for the definition of soil liquefaction.

Mechanism of Soil Liquefaction

St. Louis, Missouri

A deeper inspection has been made into the physical meaning and mechanism of the soil liquefaction.
