| 摘 要： | 1 INTRODUCTIONIn open pit mine or hydraulic engineering, therock slope with rock layer dippinS inside into slopeis always met. This kind of slope will presentfie-cural bucklins deformation in natural state orafter excavation. The interface slips and rock layerpresents tensile bendinS yield' By introdution of theCosserat type theory (She et al, 1994, 1996 ), afinite element fomulation has been established, thebending effect of rock layer in elastic--reck layer inelastic state and slippins…

| Abstract: | Two simplified
yield functions are proposed for the layered rock mass with bending effect on the basis of
two different hypotheses. By being compiled into the FEM program, they are used to
evaluate the deformation of a cantilever. The results show the two functions present
different properties one has brittle property, the other ductile, and show that they can
be combined or singly used to correctly model different kind of deformation of layered
rock mass. |
