Influence of Roughness Digitisation Error on Predictions of Discontinuity Shear Strength Open
A key component of the new stochastic approach for discontinuity shear strength (referred to as StADSS) is characterising the roughness of natural rock discontinuities at full scale to mitigate well-known scale effects on shear strength pr…

Pullout Capacity of Strip Anchors in Spatially Variable Soil. I: Clay Open
Natural soils often exhibit significant spatial variability due to their geological history of soil formation. As an attractive anchoring solution for floating offshore structures, this paper has investigated the pullout capacity of strip …

Pullout Capacity of Strip Anchors in Spatially Variable Soil. II: Sand Open
Plate anchors have been recognized as an attractive option for floating offshore structures due to their low cost and high effectiveness. The prediction of anchor pullout capacity often assumes a homogeneous sand with uniform properties ov…

Learning from prior geological information for geotechnical soil stratification with tree-based methods Open
Geotechnical subsurface stratification based on sparse measurements presents a significant challenge. Learning from prior geological information, such as learning soil layer distribution patterns from stratification results (2D images) of …

Numerical Modelling Techniques for Stability Analysis of Slopes Reinforced with Shallow Roots Open
It is well recognised that plant vegetation and roots are capable of improving the shear strength of hillslopes by reinforcing soil shear resistance. Several key factors influencing the level of slope reinforcement include root geometry, o…

Using porous random fields to predict the elastic modulus of unoxidized and oxidized superfine graphite Open
Nuclear graphite is a candidate material for Generation IV nuclear power plants. Porous materials such as graphite can contain complex networks of pores that influence the material's mechanical and irradiation response. A methodology known…

Probabilistic seismic slope stability analysis and design Open
Deterministic seismic slope stability design charts for cohesive–frictional ([Formula: see text]) soils are traditionally used by geotechnical engineers to include the effects of earthquakes on slopes. These charts identify the critical se…

Influence of Spatially Variable Soil Permeability on Backward Erosion Piping Open
Backward erosion piping (BEP) is a failure mechanism of serious concern for both dams and levees.Finite element models have been developed for analysis of BEP; however, these models often assume foundation soils are entirely homogenous.Rec…

Vertical spatial correlation length based on standard penetration tests Open
The spatial correlation length (SCL), or the scale of fluctuation, is a parameter for describing the spatial variability of soil and one of the important parameters used in random field theory. Studies reporting the spatial correlation len…

An analytical approach to assess quality control sample sizes of cement-based “solidification/stabilization” Open
This paper presents an analytical approach to selecting the sample size required to achieve acceptable quality control in a cement-based “solidification/stabilization” construction cell program intended for the treatment–containment of con…

Probabilistic considerations for the design of deep foundations against excessive differential settlement Open
Current foundation design practice for serviceability limit states involves proportioning the foundation to achieve an acceptably small probability that the foundation settlement exceeds some target maximum total settlement. However, it is…

THE STOCHASTIC FINITE ELEMENT METHOD FOR NUCLEAR APPLICATIONS Open
Nuclear materials are subjected to demanding environments, encountering high temperature gradients and fast neutron fluxes that gradually damage its structure and there-fore change the material properties. Some components of a nuclear reac…
