LEAST ENERGY PRICIPLE OF DYNAMICAL FAILURE OF ROCK MASS
岩体动力破坏的最小能量原理

Based on the fact that the released energy of dynamical failure of rock mass is more than induced energy,the inhomogeneity and anisotropy of rock mass are discussed,and the least energy principle of dynamical failure of rock mass is proposed. Different failure manners correspond to different consuming energy and stress states. The consuming energy of rock mass failure in reality is destroy energy under 1D stress state. Some engineering and laboratory cases are presented,and the study results will be beneficial to defence engineering and underground engineering.
