Jean-Pierre Giroud

Jean-Pierre Giroud (born March 13, 1938) is a French geotechnical engineer and a pioneer of geosynthetics since 1970. In 1977, he coined the words "geotextile" and "geomembrane", thus initiating the "geo-terminology".[1] He is also a past president of the International Geosynthetics Society, member of the US National Academies, and Chevalier de la Légion d'Honneur.

Education and career edit

Giroud is a civil engineer from Ecole Centrale de Paris, and he got his Ph.D. in geotechnical engineering at the University of Grenoble. He has been president of the International Geosynthetics Society (1986–1990) and director of the Geotextiles and Geomembranes Group of Woodward Consultants (1978–1983). He was the co-founder and chairman of the board of GeoSyntec Consultants (1983–2001), of which he is now chairman emeritus. He was chairman (two terms) of the Technical Committee on Geosynthetics of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). He was also co-founder and chairman of the editorial board of the two main technical journals in the field of geosynthetics engineering, Geotextiles and Geomembranes (1984–1994) and Geosynthetics International (1994–2021). Giroud is now an independent consultant since 2001.[2]

Research edit

Giroud has developed a number of design methods used in geosynthetics engineering. Examples of the design methods he developed include: liner leakage evaluation, drainage systems, leachate collection and leakage detection layers, liner system stability, reinforcement of liners and soil layers overlying voids, geomembrane stress and strain analysis, evaluation of geomembrane properties, connections between geomembranes and rigid structures, geomembrane uplift by wind, and geotextile filters. Giroud has been dubbed "the father of geosynthetic lining systems",[3] and Richardson stated that “Understanding and properly implementing the basic leakage equations developed by Giroud is key to the proper design of surface impoundments. . . Rarely does a single engineer creatively affect a particular application as much as he has.”[4] Giroud is also co-author with Professor J. Han of the Giroud-Han method for the design of unpaved roads stabilized with geosynthetics[5][6] used world wide.

Innovation edit

  • In 1973, presentation of the double liner concept,[7] which has been adopted as the basic design for hazardous waste landfills.
  • In 1989, quantification of the rate of leakage associated with composite liners,[8] which have been adopted for municipal solid waste landfills.
  • In 1995, publication of a detailed design method for the resistance of geomembranes liners to uplift by the wind,[9] which made it possible to construct landfill covers with geomembranes.

Project design edit

Giroud has worked on projects of dams, canals, reservoirs and waste storage landfills in North and South America, Europe, Africa, Middle East, Far East, Australia and New Zealand where he provided design and construction assistance. Examples include:

  • Valcros Dam, France (1970) where a nonwoven geotextile was used for the first time as a filter and where a geotextile filter was used for the first time in a dam.
  • Pont-de-Claix Reservoir, France (1974) where a double-liner with two geomembranes and a leakage detection layer was used for the first time.
  • Proton Decay Experiment Underground Reservoir, Lake Erie, Ohio, United States (1980) where an entirely geosynthetic double liner system (with two geomembranes and a geosynthetic leakage detection layer) was used for the first time.
  • Sulfuric Acid Reservoirs, Arlit Uranium Mine, Niger (1981) where a strategy for evaluating the durability of PVC geomembranes was developed.
  • New-Milford Waste Disposal Landfill, Connecticut, USA (1987), where the stability of the landfill cover was evaluated with laboratory tests and full-scale tests.
  • Delaware Solid Waste Authority Landfill, Sussex County, Delaware, USA (1998), first landfill with an exposed geomembrane cover designed to resist uplift by wind.
  • Assessment of Soil Reinforcement Products and Systems for the Geotechnical Engineering Office of the Government of Hong Kong (1999-2008).
  • Tekapo Hydroelectric Canal, New Zealand (2011-2013), where an original design method was used to evaluate the resistance of a geomembrane lining to seismic activity.
