Spatial variability of soil properties was rarely taken into account directly in traditional slope
stability analyses, rather some “average” or suitably “pessimistic” properties are assumed to …

The calculated response from a numerical model will deviate from the measured one given
the presence of modelling idealizations and real world construction effects. This deviation …

The purpose of this paper is to address the “what,”“why,” and “how” questions posed by
engineers who are not familiar with geotechnical reliability and have not kept abreast of …

The story of statistics in geotechnical engineering can be traced to Lumb's classical
Canadian Geotechnical Journal paper on “The Variability of Natural Soils” published in …

This paper adds to the ongoing discussion on the role of reliability calculations in
geotechnical design. It situates design calculations, be it verified by a global factor of safety …

In-situ and/or laboratory test data, monitoring data and other site-specific information are a
common basis for assessing geotechnical performance. This information enables one to …

Most slope collapses have three-dimensional (3D) characteristics due to the uniform soil.
The traditional plane-strain analyses neglect the 3D effects and could yield an …

Decision making in geotechnical engineering is always related to a project carried out at a
specific site. It is natural for data-driven site characterization (DDSC) to attract the most …

This paper addresses the statistical uncertainties associated with the estimation of a depth-
dependent trend function and spatial variation about the trend function using limited site …

This study proposes a subset simulation (SS)-based approach for efficient slope reliability
analysis involving copula-based cross-correlated random fields of cohesion (c) and friction …
