GENERALIZING AND MEASURING THE HVORSLEY EFFECTIVE COMPONENTS OF SHEAR RESISTANCE WITH DISCUSSION

The Hvorslev effective components are reviewed, and it is argued that the usual assumption of equal cohesion at equal void ratio can be in error because void ratio is not a sufficient description of soil structure. To avoid this error, and to permit investigating the components as functions of strain, it is necessary to redefine and generalize them. This is done. An experimental procedure, called the IDS test, is described which permits separation of the generalized components in a direct manner from a single specimen. The few available comparisons between the Hvorslev and generalized components are presented and are favorable. Discussion: Robert L. Konder, while agreeding with many of the author's points, disagrees with Schmertmann on at least four occasions: (1) Konder puts more importance on the time variable; (2) Schmertman perpertuates the cohesion and friction philosophy, which Konder considers to be nonfundamental; (3) in Konder's opinion the use of Mohr circles for separation of components at strains less than failure is theoretically unjustifies: (4) Konder sees Schmertmann's paper as implying the validity of superposition in soils and he disagrees.
