Abstract
Plastic board drain (PBD) method, one of soft ground improvement techniques, shorten drain path to accelerate consolidation process to improve shear strength of soft clay. The influence factors affecting to a degree of consolidation in PBD method are discharge capacity, smear zone, coefficient of consolidation, and surcharge loading et al. Until the present, however, deterministic methods in designing PBD method are unable to consider these factors and their uncertainties systematically. With quantitative analysis approach by statistics, it is possible to minimize errors occurred by uncertainties of influence factors in PBD design. In this paper, new probabilistic approach to overcome such issues in PBD design method has been discussed with case history. Thus, it is required to introduce a probabilistic analysis that allows this way to reflect on the outcome of consolidation analysis.
