Advances in landslide continuum dynamic modelling

摘要

Landslide continuum dynamic models have improved considerably in the past three decades,especially within the past few years,but a consensus on the best method of determining the input resistanceparameter values for predictive runs has not yet emerged. A calibration-based approach is one possible method,although different calibrated values are often obtained using different models to back-analyze the same event.These differences may be amplified by the different input geometrical assumptions made in each case. With theauthors' own models,consistent ranges of calibrated parameter values have been found for specific classes ofevents,and these ranges can be used for parametric forward-analyses. A long-term goal of this work is to builda calibration database large enough to permit probabilistic input parameter selection.
