Circular and Logarithmic Spiral Slip Surfaces

Journal of the Soil Mechanics and Foundations Division, 1969
A method of analysis of embankment stability is described which applies equally to slip surfaces having a cross section either in the form of a circular arc or a logarithmic spiral arc. The method is applied to the solution of a number of stability problems in which the slope of the embankment and the soil properties vary over a wide range.

Approximating Logarithmic Spirals by Quarter Circles

2021
The approximation of a golden logarithmic spiral by quarter circles is well known. Starting from this, we show that any logarithmic spiral can be approximated by quarter circles in a similar way. Using our construction on a rectangle with aspect ratio √휙 and performing a coordinate reparametrization, we obtain an aesthetic partition of the plane as our
