| Abstract | The undrained shear strength (s(u)) of cohesive soils is a crucial parameter for many geotechnical engineering applications. Due to the complexities and uncertainties associated with laboratory and in situ tests, it is a challenging task to obtain the undrained shear strength in a reliable and economical manner. In this study, a probabilistic model for the s(u) of moderately overconsolidated clays is developed using the Bayesian model class selection approach. The model is based on a comprehensive geotechnical database compiled for this study with field measurements of field vane strength (s(u)), plastic limit (PL), natural water content (W-n), liquid limit (LL), vertical effective overburden stress (sigma'(nu)), preconsolidation pressure (sigma'(p)) and overconsolidated ratio (OCR). Comparison study shows that the proposed model is superior to some well-known empirical relationships for OC clays. The proposed probabilistic model not only provides reliable and economical estimation of s(u) but also facilitates reliability-based analysis and design for performance-based engineering applications. |
