Abstract The aim of this paper is to present an approach for the assessment of the Serviceability Limit State (SLS) reliability of pile groups foundation combining the Ultimate Limit State (ULS) reliability method of pile groups. To this end, the linear relationship between the ULS and SLS reliability indices is presented using the formulas for calculating the ULS and SLS reliability indices of single piles. Meanwhile, the influence of system effects, correlation coefficient between pile group efficiency and system effects (ρ ζ,χ ), and limiting tolerable settlement (S lt) on the SLS reliability analysis of pile groups foundation is studied using pile load test data compiled for illustration. The results indicate that both the ULS reliability index (β G-uls) and the SLS reliability index (β G-sls) of pile groups foundation decrease with ρ ζ,χ , that powerful system effects can enhance the ULS and SLS reliability of pile groups foundation, and that β G-sls increases with S lt. the reliability level estimated by pile load test data is equivalent to that incorporating the SLS requirements with a certain value of S lt between 15 mm and 25 mm. For S lt larger than this value, Reliability-based Design (RBD) of pile groups foundation will depend on the ULS requirements, but, conversely, RBD will depend on the SLS requirements.
