Nonlinear Consolidation Analysis of Stone Column Composite Ground under Time-Dependent Loading

Abstract:

A few solutions for stone column composite ground consolidation have been presented which ignoring the nonlinear characteristic of surrounding soil or the variation of upper load with time. Considering the nonlinear characteristic of surrounding soil, variation of upper load with time, distribution of permeability coefficient in smear zone, the governing equation for consolidation of composite ground is obtained. The equation is solved using separation of variables method. Finally, the influence of parameters on consolidation rate is discussed.
