Lecture Overview
The 46th Terzaghi lecture, presented by Professor Robert Holtz, will begin with a historical review of reinforced soil technology:
- from the ancients,
- to the developments by H. Vidal and K. Lee on Terre Armée and Reinforced Earth,
- the early uses of geosynthetics for soil reinforcement in France (Bidim), Sweden (Wager and Broms),
- and the USA (USFS, FHWA, J. R. Bell, T. A. Haliburton, B. R. Christopher and others).
The advantages and basic behavior of Geosynthetic Reinforced Soil (GRS) will then be presented, with an overview of current design procedures, refering to UW analytical research results. Practical suggestions will be given for dealing with creep, pullout, and backfill drainage. Geosynthetic properties will also be discussed, again with reference to UW research results.
Although GRS is quite mature in development, a few technical and professional issues remain; primarily, too many failures of these structures occur. The lecture will conclude with reasons for these failures and suggestions as to what the profession can do about them. Several examples of successful applications of GRS and associated technology will also be presented.
This is worth upto 1.5 CPD points.
