Biopolymer combine with vegetAtion soiL treAtmeNt for stabilisation of transport infrastruCture Earthworks

Descripción del proyecto

Diseño de taludes del suelo para una infraestructura de transporte ecológica

La actual infraestructura de transporte depende en gran medida de los taludes de corte y terraplén, la mayoría de los cuales se construyeron hace más de cien años. No se diseñaron teniendo en cuenta la velocidad y la frecuencia de los vehículos ni las condiciones meteorológicas actuales. Se necesita una solución de ingeniería sostenible y con un bajo consumo de carbono para aumentar la resiliencia y proteger las explanaciones vitales para el transporte, al tiempo que se reduce el impacto en los ecosistemas y se restablece la pérdida de carbono orgánico del suelo causada por las actividades antropogénicas. El proyecto BALANCE, financiado con fondos europeos, propondrá unos métodos de bioingeniería de taludes que aprovechan la mecánica tradicional del suelo y la edafología. El equipo del proyecto llevará a cabo una modelización numérica, análisis la cuantificación de la incertidumbre, pruebas de laboratorio y de campo para encontrar una alternativa ecológica a los métodos tradicionales de ingeniería.

Objetivo

"Safe, efficient and secure transport infrastructure is a fundamental requirement to facilitate and encourage the movement of goods and people throughout not only the EU, but the whole world. The performance of these networks is critically dependent on the function of cutting and embankment slopes. Many of these transport earthworks in Europe were constructed over 100 years ago and are not designed for today’s vehicle speed, frequency and weather conditions. The long-term intensive dynamic loads generated from the moving vehicles combined with the severe wet-dry weather conditions induced by climate change, increase the likelihood of transport infrastructure earthwork failures. Subsequently, leading to costly disruption of road and rail journeys, with risk to life and property. The EU’s leading position in achieving the 2030 goal for sustainable development emphasises the urgency to develop a low-carbon, and sustainable engineering solution that not only can increase resilience and protect vital transport earthworks, but also to reduce the impact on ecosystems and restore soil organic carbon loss caused by human activities. The conventional engineering orientated solution alone is insufficient to solve the problem. Therefore, this fellowship leverages traditional soil mechanics with soil science through new insightful numerical modelling, UQ analysis, laboratory and field tests to advance slope bioengineering methods (SBMs) by utilising biopolymer and vegetation together for the reinforcement. This technique is an aesthetically-pleasing, environmentally and ecologically-friendly alternative to traditional ""hard"" engineering methods, providing the additional environmental and societal benefits of carbon fixation, enhanced biodiversity and ecosystem restoration within the built environment. The knowledge and tools from this project can potentially be utilized in other areas, e.g. river bank, sand dunes, flood embankments management and agricultural and amenity systems."
