...R. B. A. de Sousa; A. K. Leung; J. A. Knappett; X. Zhang Plant root–soil mechanical interaction in the application of soil bioengineering such as tree and slope stability has been investigated by way of centrifuge modelling, utilising root analogues to replicate vegetated soils. Three-dimensional...

...A. Yildiz; F. Graf; S. M. Springman Mechanical contribution of roots to the shear strength of saturated soils is not the only function of vegetation in favour of slope stability. Plants also cause an increase in the strength due to plant-induced suction, resulting from partial saturation. Although...

... induces desiccation cracks and also lead to water-stressed condition of plants. The use of organic materials is advocated in green infrastructure for increasing water retention and ground-covering ability of vegetation. The main objective of this paper is to explore the influence of inclusion of waste WH...

... soil conditions, namely soil with and without tree (Schefflera heptaphylla), biochar-amended soil (BAS) with and without tree, were subjected to drying. Three replicates were considered for each vegetated soil. By adding 10% (v/v) of biochar, the optimum water content of soil increased from 12...

... of drying, the vegetated nutrient-supplied soil induced 15–50 kPa higher suction than the vegetated nutrient-poor soil due to the higher RAI, LAI and root volume of the plants grown in nutrient-supplied soil, which enable plants to absorb and transpire more water. In contrast, the water-retention ability...

...C. W. W. Ng; J. J. Ni; A. K. Leung; Z. J. Wang Vegetation can affect soil hydrology not only through evapotranspiration but also through changes in soil water retention curve (SWRC). Models that are able to predict root-induced change in SWRC are limited. Such models often contain many empirical...

... reserved 2014 centrifuge modelling partial saturation suction vegetation The pull-out resistance of a plant root system is recognised as a key contribution to the mechanical stabilisation of vegetated soil slopes (Waldron & Dakessian, 1981 ; Ennos, 1990). Various studies have...

...C. W. W. Ng; R. Yu Although geotechnical centrifuge modelling of vegetated slopes has become increasingly popular, attention has been mainly focused on modelling the mechanical effect of roots. The hydrological effect, namely, water uptake and thus induced negative pore-water pressure (PWP), has...

To solve this problem, mechanical methods such as soil nailing, retaining walls and geosynthetic reinforcement have...
