Abstract

This paper is the second of a two-part study that assesses the influence of undulating shear surfaces on the effective stress across a shear zone during rapid shearing. This part of the study uses the simple model developed in part one to investigate the influence of rate of shearing, undulation geometry, soil thickness and total normal stress on pore water pressure generation in the shear zone. These preliminary investigations illustrated a correlation between pore water pressure generation and the negative rate behaviour associated with many long run-out landslides. Therefore additional investigations have been conducted and compared with laboratory testing in the NGI/IC ring shear apparatus in which negative rate effects have been recorded and pore water pressures monitored in association with undulating shear surfaces. These comparisons are presented here and it is shown that the model has merits and illustrates the potential for further development.
