The concrete tower silo has been a popular and efficient structure for storing silage on Canadian farms for about four decades. By the end of 1978 there were 9430 silos in Quebec alone (M. Fortier 1978, pers. commun.). Large concrete tower silos evolved over this time from the original, mainly wooden structures, but most of the development went into the super structure and mechanical plant for handling silage. The design of the foundations with respect to bearing capacity of the sup porting clay soils was largely ignored, with the result that many of the structures settled and tilted various amounts and even overturned on occasion. As the proportion of large tower silos has grown over the past 10-15 yr, the number of problems has increased alarmingly. Research work conducted in the province of Ontario related many problems such as excessive settling, tilting, and bearing capacity failure to inadequate foundations (Eden and Bozozuk 1962 Bozozuk 1972, 1974, 1976, 1979a,b Lo and Becker 1979).
