Abstract
In the process of rock mass failure,energy dissipation and energy release is the inherent power of rock damage and failure,and may cause rock burst power disasters of rock under different stress paths.In view of the energy dissipation problem of rock mass under different dynamic stress conditions.In this paper,the energy dissipation and release of rocks under different stress paths are summarized based on the existing literatures.It is shown that it is not comprehensive to consider the energy consumption of rock failure process under the condition of one-dimensional dynamic stress, and energy dissipation is an effective and feasible method to judge the damage degree of rock micro cracks.The energy consumption is insufficient under cyclic loading and unloading path.Bedded composite rock is the weak link of the rock mass structure,has an important effect on the stability of rock mass.it is necessary to further the dynamic characteristics on the energy dissipation law of the mechanical properties.And expected to correctly evaluate the mechanics and energy consumption characteristics of rock failure process through the analysis and comparison.
