About this event

Engineers should be able to design reinforced soil structures using marginal, poorly drained fills, without the need to import granular material, which has both cost and environmental implications. Marginal fill typically has high silt and/or clay content which, when loaded, generates pore water pressure in the backfill. This reduces the soil's effective strength and the bond between reinforcement. Thus, marginal fill can only be used in reinforced soil structures if adequate drainage is provided.

This sustainable and environmentally friendly slopes and walls can be achieved using the combined reinforcement and drainage geogrid (herein referred to as "drainage geogrid").

The aim of this presentation is to introduce with real case studies in the UK an innovative design methodology and approach for reinforced slopes and walls with low-permeability fills. The design and construction experience developed in the UK during 2015 and 2016 will be presented to confirm the effectiveness of the design and the system proposed.
