| Research Abstract |
In order to clarify the mechanisms of large landslides due to earthquakes field investigation, soil sampling, dynamic element tests of undisturbed soils and rocks, model experiments and numerical analyses are carried out. The mechanism of soil slope failures which are often seen in Japan is found to be due to the abrupt reduction of soil shear strength by cyclic shear. The mechanism of weathered rock slope failures is found to be classified into rock avalanche and jointed rock slope failures. Some parts of their mechanism are clarified mainly by model tests.
