Topic:

Determining the strength of geosynthetic reinforcement

Course overview:

Since the introduction of geosynthetic reinforced soil in the 1970’s, further research has been undertaken to provide a complete understanding of the behaviour of geosynthetic reinforced soil structures under different loading conditions.

This has led to an increase in the number of geosynthetic reinforcement types available in the market which raises the question, has new manufacture matched the level of testing required to establish the material properties needed for design?

This webinar will focus on the material properties and associated testing required for determining the design strength of geosynthetic reinforcement, starting from the short-term tensile strength and then considering the reduction factors for creep, installation damage and durability.

Speaker:

Gordon Stevens is Technical Manager for Geofabrics New Zealand. He holds a 4 year Higher National Diploma in Civil Engineering and has been involved in the design and use of geosynthetics into infrastructure projects throughout New Zealand, the Pacific and Papua New Guinea for over 30 years. A member of the International Geosynthetic Society, Gordon’s area of expertise includes reinforced soil and retaining wall design where he has delivered numerous training courses and technical papers.

Learning Outcomes:

• Understanding the various forms of geosynthetic reinforcement
• How the tensile properties of geosynthetics are affected by factors such as creep, installation damage and environmental conditions
• Learning to calculate the long-term strength of geosynthetic reinforcement
