Abstract:
By means of 3D plasticity limit analysis method and virtual work rate equation in limited state, the upper bound solution of safety factor can be derived when hexahedral sliding wedge for the rock slope stability is treated as study object. A typical example is used to prove the new method mentioned in the paper; moreover, the authors compare the method with 2D rigid body limit equilibrium method which has been introduced by Professor Hoek. The results show that based on rigidplastic presumption and virtual workrate theorem, not only the stress analysis on sliding surface can be avoided, but also the complicated calculation can be simplified, the new method has many advantages, such as correctness for analysis conclusion, clarity of formulaic concept, succinctness of algebraic expression, facility for use etc. 1 tab, 4 figs, 12 refs.
