Abstract
The paper describes some geotechnical properties of the soft soils in Guangzhou College City, China, which are difficult to both sample and test. Laboratory and in situ tests were carried out to assess the physical and mechanical indices of the soils. The data were statistically analyzed and linear regression undertaken such that equations could be developed by which the geotechnical properties of the soft soils can be predicted. The statistical validity of the degree of correlation confirmed that using these equations, the mechanical indices can be estimated from physical indices determined by routine testing.
Résumé
L’article présente quelques caractéristiques géotechniques de sols mous, difficiles à prélever et tester, présents sur le campus universitaire de Guangzhou (Chine). Des essais de laboratoire ou in situ ont été réalisés afin d’évaluer différents indices physiques ou mécaniques. Les résultats d’essais ont fait l’objet de traitements statistiques et des régressions linéaires entre paramètres ont été établies afin d’obtenir des relations permettant de prévoir certaines propriétés géotechniques concernant ces sols mous. Les coefficients de corrélation obtenus par ces traitements statistiques permettent d’indiquer que les indices mécaniques considérés peuvent être estimés à partir des indices physiques établis par des essais de routine.
