Overview

A two-day course to help understand geosynthetics materials and design soil reinforcement structures. (walls, steep slopes, embankments and pavement structure)

Why Should an Individual Attend?

The course helps graduates to apply their theoretical training in practice. It is therefore recommended for:

• Staff working in the industry with very little experience or who are about to become involved in designing of soil reinforcement structures
• Candidate engineers, technologist and technicians
• Experienced personnel looking for a refresher course in geosynthetics in soil reinforcement

Benefits include:

• Participation in an interactive workshop
• Practical activities for assessing geosynthetics properties for soil reinforcement
• Design examples on design software (available free of charge)
• CPD credits

Outcomes

Attend this course and learn about:

• Geosynthetics material for soil reinforcement
• Soil reinforcement principles
• Design of walls and steep slopes
• Design of embankments (soft soil, piles, and sinkholes)
• Design of pavement structure

Program Outline

INTRODUCTION

• Why soil reinforcement?

INTRODUCTION TO GEOSYNTHETICS

• Geosynthetics products
• Geosynthetics functions

GEOSYNTHETICS FOR SOIL REINFORCEMENT

• Short term properties
• Long term properties
• SANS 20432 - assessment of geosynthetics for soil reinforcement
• Exercise - assessment of geosynthetics in short and long term

DESIGN OF WALLS AND SLOPES

• Components (facing, foundations, reinforcement, drainage)
• Design codes (SANS 207, FHWA etc.)
• Design principles, internal, overturning, sliding, bearing capacity analyses
• Exercise - Design a soil reinforcement structure (Using hand calculations, excel spreadsheet and freeware software)

DESIGN OF BASAL REINFORCEMENT

• Principles
• Embankments on soft soil
• Embankments on piles
• Embankments over sinkholes
• Exercise - Design a basal reinforcement structure (Hand calculations)

DESIGN OF GROUND REINFORCEMENT FOR ROADS

• Geosynthetics in the subbase
• Geosynthetics in the base
• Geosynthetics in the wearing course
• Geosynthetics in the overlay
• From design to construction - QA and QC on geosynthetics

Who Should Attend?
