Changes in the course of constant loading consolidation in soil with modeled granulometric composition contaminated with petroleum substances

Abstract The effect of contamination with petroleum substances (A1 jet fuel and 15W40 mineral oil) on the compressibility consolidation mixtures ice-dammed clay aeolian sand was determined in a Barden–Rowe consolidometer adapted for liquid-phase tests. deterioration filtration capacity contaminated soil medium relative to non-contamination condition is reflected by mobilization higher values pore pressure u b water parameter C CL course As consequence, lower modulus M 0 coefficient c v are obtained relation results uncontaminated samples. This generally indicates changes parameters presence tested contaminants. Methodologically, delay onset steady-state phase constant loading (CL) observed soils. provides rationale programming tests at rate. At same time, unified model characterization – T allows us assess reliable nature results. one recommend CRL (constant rate loading) as tool determining properties cohesive soils design isolation barriers.
