초록

Jointed rock is often modeled using ubiquitious joint models, anisotropic plasticity models with yield condions that simulate slip along joint sets. In this paper, a ubiquitous joint model is derived for a rock mass cut by two sets of continuous joints. The model is used to compute the bearing capacity of a footing resting on jointed rock. Comparison to a series of Distinct Element simulations with different joint spacings, suggests that ubiquitous joint modles are only appropriate when the joint spacing is small.
