摘要：

In this paper, the evolution of damage in jointed rocks or concrete is presented as the main form of failure of engineering structures. The damage evolution law for jointed rocks is proposed based on thermodynamics. By spectral analysis of eigenvalue of the bifurcation equations, a method for structures failure is presented. According to theoretical results, the numerical simulation of the collapse and the capacity of dams can be implemented. The results illustrated in this paper from the numerical simulation are approximately consistent with that of physical tests.
