View article: Internal erosion of a gap-graded soil and influences on the critical state
Internal erosion of a gap-graded soil and influences on the critical state Open
Water retaining structures are critical elements of civil infrastructure. Internal erosion of soils forming the containment structures may occur progressively and lead to expensive maintenance costs or failures. The strength, stress–strain…

New modelling tools for quantification of mechanical reinforcement of soil by plant roots Open
<p>Plant roots can help to stabilise riverbanks and slopes by providing additional mechanical reinforcement through tensioning of root material. This problem has typically been studied at the ultimate limit state, focussing on quanti…

DRAM: A three-dimensional analytical model for the mobilisation of root reinforcement in direct shear conditions Open
Roots can stabilise slopes against shallow landslides by mobilising their mechanical strength. Existing analytical models are highly simplified and typically focus on the ultimate limit state only, thus providing little insight into the un…

Root reinforcement: continuum framework for constitutive modelling Open
The mechanical contribution of plant roots to soil strength has typically been studied at the ultimate limit state only. Since many geotechnical problems are related to serviceability, such as deformation of infrastructure, a new constitut…

Reoccupy Earth [Table of Contents] Open
Habit rules our lives. And yet climate change and the catastrophic future it portends, makes it clear that we cannot go on like this.\nOur habits are integral to narratives of the good life, to social norms and expectations, as well as to …

Root branching affects the mobilisation of root-reinforcement in direct shear Open
The contribution of roots to the mechanical behaviour of soil has typically only been studied for the ultimate limit state. In these approaches, roots are typically modelled as straight and unbranched structures. This approach overlooks th…

Analysis of coupled axial and lateral deformation of roots in soil Open
Summary Plant roots can help to stabilise slopes. Existing analytical models to predict their mechanical contribution are however limited: they typically focus on the ultimate limit state, employ various empirical factors, and ignore much …

Construction of simplified design <i>p</i>–<i>y</i> curves for liquefied soils Open
In practice, laterally loaded piles are most often analysed using a ‘beam-on-non-linear-Winkler-foundation’ approach, whereby the soil–structure interaction is modelled by means of p–y curves. Although well-calibrated p–y curves exist for …

Fibres and soils: A route towards modelling of root-soil systems Open
The addition of flexible fibres to granular, cohesionless soils, has a marked influence on the stress:strain and volumetric response. Experimental observations provide inspiration for the development of continuum models for the mechanical,…

Memory Surface Hardening Model for Granular Soils under Repeated Loading Conditions Open
The prediction of the stress-strain response of granular soils under large numbers of repeated loading cycles requires subtle changes to existing models, although the basic framework of kinematic hardening/bounding surface elastoplasticity…

Analysis of consolidation with constant rate of displacement Open
The “constant rate of strain” consolidation test has been widely used for several decades to provide a continuous load–displacement response. An exact theoretical solution can be obtained for this consolidation problem. Two other solution …

Experimental investigation of wave propagation in three dimensions in unbounded particulate assemblies Open
Understanding wave propagation through soils is essential for site response analysis in earthquake engineering, interpretation of geophysical surveys and SASW (Spectral Analysis of Surface Waves), interpretation of laboratory bender elemen…
