Reliability-Based Verification of Serviceability Limit States of Dry Deep Mixing Columns

Deep mixing columns commonly are used to reduce settlement under road and railway embankments on soft soils. However, the structural behavior of soil volume improved with is difficult predict, due existence considerable uncertainties in process interaction between untreated soil. This paper probabilistically investigated two serviceability limit states deep from a system reliability perspective. A design framework employing observational method proposed that considers allowable residual settlements, excessive column yielding, curing time columns. The facilitates an effective reduction geotechnical uncertainty during construction promotes risk-aware decision-making both embankment.
