One-dimensional self-weight consolidation of a lumpy clay fill The need to use a large amount of dredged and excavated materials as fill for land reclamation necessitates an examination of the consolidation of a lumpy fill. Experimental results have shown the existence of two systems of voids in such a fill: inter-lump voids and intra-lump voids. The consolidation of this fill is highly complicated, and a simple box-spring model analogy is used to pr... ...

Soil deformation measurement using particle image velocimetry (PIV) and photogrammetry A deformation measurement system based on particle image velocimetry (PIV) and close-range photogrammetry has been developed for use in geotechnical testing. In this paper, the theory underlying this system is described, and the performance is validated. Digital photography is used to capture images of planar soil deformation. Using PIV, the movement of a fine mesh of soil patches is meas... ...

The effects of drainage on the behaviour of railway track foundation materials during cyclic loading This paper presents the results of a series of hollow cylinder tests carried out to investigate the role of drainage conditions on the response of railway track foundation materials during cyclic loading. Three sand–clay mixes were tested. It was found that, below a certain cyclic shear stress threshold, and depending on the drainage conditions, changes in principal stress direction shoul... ...

Sand grain crushing and interface shearing during displacement pile installation in sand Particle crushing, shear banding, interface abrasion and migration of crushing products all have the potential to influence the behaviour of displacement piles in sands. This paper considers these particulate processes, reporting experiments with model displacement piles installed in uniform pressurised sand and parallel interface ring shear tests. The findings offer new insights into the... ...

Tunnelling and geotechnics: new horizons New developments in both the theory and the practice of tunnelling are covered in the lecture. The important relationship between tunnelling and geotechnics is highlighted, and recent advances in research and practice are described, drawing on model studies, theoretical developments and field measurements from case histories from around the world. Simplified plasticity models are presente... ...

Analysis of undrained soil deformation due to ground loss Closed form solutions are presented for obtaining the strain field in an initially isotropic and homogeneous incompressible soil due to near-surface ground loss. This problem fits into a category of cases in which the imposed boundary conditions are only or mainly in terms of displacements (strain-controlled problems). In these cases there is a possibility of eliminating the stresses and ... ...

PISA design model for monopiles for offshore wind turbines: application to a stiff glacial clay till Offshore wind turbines in shallow coastal waters are typically supported on monopile foundations. Although three-dimensional (3D) finite-element methods are available for the design of monopiles in this context, much of the routine design work is currently conducted using simplified one-dimensional (1D) models based on the p–y method. The p–y method was originally developed for the relati... ...

Design method for the undrained capacity of skirted circular foundations under combined loading: effect of deformable soil plug The response of skirted circular foundations with rough and smooth soil–skirt interface to combined loading is investigated. The shape and size of the failure envelopes of the skirted circular foundations under a practical range of embedment ratio, soil strength heterogeneity, soil–skirt interface and level of vertical mobilisation are compared to those of solid embedded circular foundati... ...
