Abstract
Silos were constructed in the early 1970s in most parts of Canada on soft deposits by farmers with no or little technical assistance. The majority of these silos constructed on weak compressible deposits have overturned/tilted, and some even collapsed due to inadequate or insufficient bearing capacity and/or differential settlement and tilting. Bozozuk [1, 2] documented some of these failures and analysed the same based on the available theory of bearing capacity of foundations on homogeneous ground. The current study reassess two cases based on current and recent theories of bearing capacity of foundations on normally consolidated ground (strength increasing with depth, Davis and Booker [4]) with desiccated layer over it. A simple theory for bearing capacity of foundations on desiccated layer overlying a normally consolidated soil with undrained strength increasing linearly with depth is developed as an extension of Meyerhof’s theory for two-layered soil. The stability of the silos is reassessed based on the proposed approach.
