Characterization of geotechnical variability
Kok-Kwang Phoon,Fred H. Kulhawy +1 more
TLDR
In this paper, the three primary sources of geotechnical uncertainties are inherent variability, measurem, and measurem uncertainties, and the three main sources of variability are measurem and inherent variability.Abstract:
Geotechnical variability is a complex attribute that results from many disparate sources of uncertainties. The three primary sources of geotechnical uncertainties are inherent variability, measurem...read more

Evaluation of geotechnical property variability
Kok-Kwang Phoon,Fred H. Kulhawy +1 more
TL;DR: In this paper, the authors evaluate geotechnical variability on a general basis that will facilitate the use of reliability-based design procedures, and assess inherent soil variability, measurement error, etc.

Bearing-capacity prediction of spatially random c ϕ soils
Gordon A. Fenton,D. V. Griffiths +1 more
TL;DR: This paper used random field theory and elasto-plastic finite element analysis to evaluate the extent to which spatial variability and cross-correlati cation is associated with spatially varying shear strengths.
Journal ArticleDOI
Prediction of undrained shear strength using extreme gradient boosting and random forest based on Bayesian optimization
TL;DR: Novel data-driven extreme gradient boosting (XGBoost) and random forest ensemble learning methods are applied for capturing the relationships between the USS and various basic soil parameters to predict undrained shear strength of soft clays.
Journal ArticleDOI
Techniques for evaluating the performance of landslide susceptibility models
TL;DR: Different techniques to evaluate model performance are discussed and tested using shallow landslide/debris-flow susceptibility models recently presented in the literature and an evaluation technique based on the minimization of costs that may arise from the adoption of the model as a land management regulatory tool is presented.

Random Fields: Analysis and Synthesis.
J. K. Ord,Erik H. Vanmarcke +1 more
TL;DR: The purpose of this book is to bring together existing and new methodologies of random field theory and indicate how they can be applied to these diverse areas where a "deterministic treatment is inefficient and conventional statistics insufficient."
Book
Random fields, analysis and synthesis
TL;DR: In this paper, the authors review the classical theory of multidimensional random processes and introduce basic probability concepts and methods in the random field context and give a concise amount of second-order analysis of homogeneous random fields in both the space-time domain and the wave number-frequency domain.
Journal ArticleDOI
Probabilistic Modeling of Soil Profiles
TL;DR: In this paper, the authors proposed a technique of modeling the statistical character of soil profiles, which provides a format for quantifying the information gathered during site investigation and testing, about the subsurface conditions at a site.
