Abstract

During the 2003 Sanriku-Minami earthquake, Japan, a flowside was triggered on a slope of about 13.5°. To study the trigger and movement mechanisms of this landslide, field investigation and laboratory ring-shear tests were performed. Field investigation revealed that the landslide originated from a fill slope, where a gully was buried for cultivation some decades ago, and shallow ground water was present. By using a newly developed undrained ring-shear apparatus, a series of undrained and partially drained shear tests was performed on samples taken from the landslide source area. Based on the test results, the triggering and movement mechanisms were examined and are discussed herein
