FINITE ELEMENT MODELING CRITERIA FOR UNDERGROUND OPENINGS IN ROCK

Modeling criteria for plane strain finite element analyses of underground openings in homogeneous, linear elastic rock are presented. The studies show that; (1) arbitrary, linear strain quadrilateral elements are most appropriate; (2) incremental excavation should be modeled using the techniques presented; (3) a minimum of 125-150 elements should suffice for simple opening systems; and (4) finite element mesh boundaries should be at 6 radii away from the to insure reasonable accuracy. The basic ideas presented can be readily extrapolated to more complex systems. /Author/TRRL/
