Infiltration rate affects slope stability by determining the of water transport to potential failure planes. This note considers influences vegetation (grass and willow) establishment root growth dynamics on infiltration rate, as related establishing bioengineered slopes. Soil columns silty sand with without were tested constant-head tests at 2, 4, 6 8 weeks after planting. increased linearly plant age below-ground traits including biomass length density. for willow-rooted soil was an order...
Understanding root-reinforcement of vegetated slopes is hindered by the cost and practicality full scale tests to explore global behaviour at slope scale, idealised nature smaller-scale testing date that has relied on model root analogues. In this study we investigated potential use living plant roots in small experiments failure would a geotechnical centrifuge achieve soil stress states comparable those field homologous points. Three species (Willow, Gorse Festulolium grass), corresponding...
Many natural and man-made slopes are planted with vegetation, it is known that this can increase the stability of under static conditions. There anecdotal evidence vegetated also perform better than fallow during earthquakes. However, study dynamic behaviour species having dichotomous (‘woody’) roots relatively rare owing to extreme expense difficulty involved in conducting full-scale testing on shrubs trees. In paper, centrifuge supporting numerical modelling have been conducted problem....
This paper presents an investigation into the influence of slope height on role vegetation to improve seismic stability. Dynamic centrifuge modelling was used test six models with identical soil properties and model geometry within different centrifugal acceleration fields (10g 30g, respectively) representing 1:10 1:30 scale slopes, that is, slopes at prototype scale. A three-dimensional (3D) root cluster analogue a tap-root system, area ratio, distribution length representative tree (of...
This paper presents a comparative study of three different classes model for estimating the reinforcing effect plant roots in soil, namely (i) fibre pull-out model, (ii) break models (including Wu and Waldron's Model (WWM) Fibre Bundle (FBM)) (iii) beam bending or p-y (specifically Beam on Non-linear Winkler-Foundation (BNWF) models). Firstly, prediction root reinforcement based being dominant mechanism potential slip plane depths was proposed. The resulting calculated were then compared...
Abstract Aim (1) To understand the tree root-soil interaction under lateral and moment loading using a physical modelling technique; (2) detect possible factors (e.g. root architecture, water condition, stress level) influencing tree’s push-over behaviour; (3) identify suitable scaling laws to use in modelling. Methods Two 1:20 scaled models with different architectures (namely, deep narrow, shallow wide) were reconstructed 3D printed based on field-surveyed architecture data. Push-over...
Understanding the stability of trees under lateral loads arising from natural hazards (e.g. extreme weather and debris flows) is important, as fallen can become a potential threat to life infrastructure. Two 1 : 20 scale three-dimensional printed analogue root system models, with architectures field-surveyed architecture data, were used simulate push-over behaviour in silty sand different conditions centrifuge. The peak overturning moments obtained verified against data field winching tests....

Large language models (LLMs) have demonstrated remarkable proficiency in mainstream academic disciplines such as mathematics, physics, and computer science. However, human knowledge encompasses over 200 specialized disciplines, far exceeding the scope of existing benchmarks. The capabilities LLMs many these fields-particularly light industry, agriculture, service-oriented disciplines-remain inadequately evaluated. To address this gap, we present SuperGPQA, a comprehensive benchmark that...
In patients with symptomatic intracranial atherosclerotic stenosis (sICAS), recent evidence has suggested an association between artery-to-artery embolism (AAE) and cortical borderzone (CBZ) infarcts. We recruited 50-99% anterior-circulation sICAS in this cohort. Stroke mechanisms were categorized as isolated parent artery atherosclerosis occluding penetrating (PAO), AAE, hypoperfusion, mixed mechanisms, using two classification systems. Classification I, the probable stroke of internal CBZ...
To effectively utilize the solid waste-soda residue (SR) and fly ash (FA), a mixture of 70% SR, 20% FA, 10% clay was formed to produce soda soil (SRS). By adding cement and/or lime, four different SRS proportions were prepared. The compaction properties, mechanical dry–wet stability. Furthermore, mechanisms explored, improvement effect efficiency lime on performance analyzed. results show that is lightweight easy compact shape, which conducive construction. Compared cement, has greater impat...
Summary Plant roots can help to stabilise slopes. Existing analytical models predict their mechanical contribution are however limited: they typically focus on the ultimate limit state, employ various empirical factors, and ignore much of underlying root‐soil interaction. A new model was developed based large deflection Euler‐Bernoulli elastic beam theory that be used study mobilisation root strength under loading conditions (direct shear pull‐out). Both lateral axial by soil were...
This paper investigates the seismic performance of rooted granular slopes using dynamic finite-element analysis, validated against recently published centrifuge test data. The importance selecting suitable strength parameters to represent soil response within a strain-hardening constitutive model was demonstrated and simulations suggested that any boundary effects introduced through use equivalent shear beam container in are negligible can be represented by semi-infinite lateral condition....
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 underlying mechanism of reinforcement mobilisation. A new model ('DRAM') was therefore developed to predict root as a function direct shear displacements. This accounts for elasto-plastic behaviour, three-dimensional orientations, failure through breakage or...
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 serviceability, such as deformation infrastructure, a new constitutive modelling framework is introduced. rooted treated composite material with separate relationships for and roots, comprehensive stress–strain relationship root constituent presented. model compared direct shear experiments on field reinforced gorse, grass...
For smaller lateral plant roots in coarse-grained soils, a potentially large relative size of soil particles compared to the may affect their transverse resistance. Even for larger trees, particle effects be important, e.g. when testing 1:N reduced scale models geotechnical centrifuge. The Discrete Element Method (DEM) was used investigate this problem. A rigid root segment under loading plane strain simulated and with Finite (FEM) simulations, where modelled as continuum (no effects). at...
The contribution of roots to the mechanical behaviour soil has typically only been studied for ultimate limit state. In these approaches, are modelled as straight and unbranched structures. This approach overlooks fact that may have deform significantly mobilise their strength, a process will be influenced by root architecture effects such branching, amongst others. Sequential mobilisation affects peak root-reinforcement, thus differences in important consider when quantifying...
