The Art of Numerical Modeling in Geomechanics

Publication: Geo-Congress 2020: University of Minnesota 68th Annual Geotechnical Engineering Conference (GSP 321)

ABSTRACT

Numerical modeling is used extensively in the design and evaluation of projects that involve the behavior of rock, soil, and groundwater. There are many potential pitfalls for the modeler, particularly if inexperienced, some of which are discussed. The importance of understanding mechanisms is stressed, and this point is illustrated with examples that show the advantages of building simplified models in addition to detailed models for site analysis.
