Probabilistic stratification method for heterogeneous soils using outlier analysis

이질적 지반의 확률적 지층구분을 위한 이상치 분석의 적용

Subsurface investigation results obtained from soils with strong heterogeneity sometimes show a high level of uncertainty about stratigraphy and mechanical characteristics. In these cases, important engineering judgments are dependent on the personal experiences of engineers. However, many of such problems can be solved by applying appropriate statistical approaches. This study introduces the outlier analysis as a one of the statistical solutions and a simple case study is presented as an example.
