Stabilisation of the Jackfield slope at Ironbridge Gorge, Shropshire

A hybrid stabilization scheme effectively addressed slope instability at Jackfield, Ironbridge Gorge, UK, by leveraging the Viggiani method to mobilize passive resistance from stable ground and transmit it into the slide mass. The design carefully balanced geotechnical and structural factors of safety using numerical examples, avoiding compounding risks. Key innovations included precise pile strength determination and optimized spacing, ensuring both stability and cost-efficiency. This approach offers a robust model for mitigating landslide risks in young geological formations prone to instability.
