USE OF CYCLOIDAL ARCS FOR ESTIMATING DITCH SAFETY

Based on the assumption that shearing stress greater than the shearing strength at any point along the surface of a ditch will inevitably result in failure, the author conducted an analysis of a cycloidal failure at the bottom of the open cut. A discussion of this cycloidal failure in the case of a vertical slope is presented, with supporting mathematical data. If the strength is exceeded, localized failure must be opposed by soil stress, which will result in general shear failure. A possibility of safety resides in the fact that the well failure will be in plane strain instead of unconfined compression.
