dc.description.abstract | The post-failure mechanism associated to Norwegian quick clay landslides is a
complex natural phenomenon. An attempt is made in the present study to
characterize the mobility of such landslides on the basis of well-documented cases
and available relationships from laboratory data. Factors affecting mobilization into
flows and run-out distances are discussed. During a landslide the flow behavior can
be quite complex and various types of flow behavior can exist depending on the
clay type, sensitivity, remoulded shear strength, pore-water salinity, mineralogy,
and water content. Results show that the remoulded shear strength in soil
mechanics is similar to values of yield strength in rheology. There is, however, a
large discrepancy between values of viscosity determined empirically from
laboratory data and those obtained from back-calculation of landslide events.
Hence, there is a need for field and laboratory calibration of these models. | no_NO |
