Overview
Construction of this 67-metre-high reinforced soil slope (RSS) was completed in December 2006. After seven years in-service, a tension crack was observed at the top of the slope.
In March 2015 this RSS structure catastrophically collapsed. The structure collapsed in a compound failure mode; as the failure plane passed beneath, partially behind, and partially through the reinforced soil mass. The RSS collapse occurred after 8.3 years in-service as the shear strength along the shale-claystone foundation interface decreased and approached the fully softened strength.
This webinar will cover the forensic investigation performed, the causes of the failure and lessons learned.
This is a joint event with the International Geosynthetic Society (IGS) UK Chapter.
