State of the art: limit equilibrium and finite-element analysis of slopes. discussion and closure
TLDR
In this paper, the authors focus on measurement of shear strength for use in slope stability analyses, asserting that laboratory tests should be performed using the same range of pressures as will act on the shear plane in the field.Abstract:
A discussion of a paper with the aforementioned title by J.M. Duncan, published in this journal (Volume 122, Number 7, July 1996), is presented. The discussion focuses on measurement of shear strength for use in slope stability analyses, asserting that laboratory tests should be performed using the same range of pressures as will act on the shear plane in the field. It is maintained that when the failure envelope is curved, strength tests at high pressure may overestimate the strength of the soil at low pressure. Discussion is followed by closure from the author.read more
