An approach for modelling spatial variability in permeability of cement-admixed soil

Abstract This paper presents a framework for modelling the random variation in permeability cement-admixed soil based on binder content and thereby relating coefficient of to unconfined compressive strength clay. The strength–permeability relationship was subsequently implemented finite element method (RFEM). effects spatial both clays RFEM is illustrated using two examples concerning one-dimensional consolidation. Parametric studies considering different scale fluctuation configurations were performed. Results show that variability clay variable can significantly influence overall consolidation rate, especially when high. However, rates also depend largely prescribed scales fluctuation; cases where horizontally layered, stagnation pore pressure dissipation may occur due soft parts yielding.
