Controlling settlements and elongation in piggy-back liners: Designing geogrid reinforced bridging layer
This webinar presents the design procedure for designing a geogrid reinforced bridging layer to control settlements in piggy-back landfills. Different design methods including British standards method, German methods, and “Soft Spot” design method will be presented and discussed. International and local case studies will be presented at the end.
Key Learnings:
- Why it is important to control settlements in piggy-back landfills
- How to design a geogrid reinforced bridging layer according to different design methods
- Important design criteria for this application
- Important geogrid performance parameters for this application
- How to model settlements
