具有弯曲效应的三维层状岩体屈服准则

A Three-dimensional Yield Criterion for Layered Rockmass with Bending Effect Considered

基于Cosserat介质理论，针对具有弯曲变形效应的层状岩体，建立了考虑弯曲屈服效应的屈服准则。初步计算表明，所建立的屈服准则是合理的。

On the basis of the Cosserat medium theory and with the bending effect being taken into consideration, we have established the yield criterion for layered rockmass, which are prone ic bending deformation. The calculation of a cantilever has demonstrated that the criterion established is correct.
