Some Plasticity Solutions Relevant to the Bearing Capacity of Rock and Fissured Clay

摘要

The report is concerned with examining the theoretical effects of semi-brittle behaviour and of the presence of defects on the stability of soil and rock masses. For simplicity, attention is restricted to surface bearing capacity of the mass under plane strain conditions, and, for the most part, ignoring the effect of density of the material. Attention is also restricted to failure of the mass due to a monotonically increasing load or single load application, but an aside on the subject of incremental failure for cyclic loading is worth making.
