Reliability-based verification of serviceability limit states of dry deep mixing columns

Spross, J., Bergman, N. and Larsson, S. (2021) Reliability-based verification of serviceability limit states of dry deep mixing columns. ASCE Journal of Geotechnical and Geoenvironmental Engineering 147(3): 04020183. DOI: 10.1061/(ASCE)GT.1943-5606.0002458.

This paper probabilistically investigated two serviceability limit states of deep mixing columns from a system reliability perspective. A design framework employing the observational method is proposed that considers allowable residual settlements, excessive settlement from column yielding, and the curing time of the columns. The design framework facilitates an effective reduction of the geotechnical uncertainty during construction and promotes risk-aware decision-making during both design and construction of the embankment.
