Abstract: With the development of the highway, the slope engineering is increasingly manifold in many different ways. For the sake of recognizing the characters of excavation engineering rock mass in nature, authors, who are based on the factors influencing the slope, the deformation and destruction characters and discussed, the methods of rock mass mechanical analysis and the numerical simulation of the slope engineering rock mass are proposed and carrieded. Some results are achieved in research. The characters of deformation and destruction of the slope is not alike that of the regular loading rock action, but according to unloading rock mass mechanics action. The stability analysis of slope rock mass must attach importance to hydraulics and unloading effect, at the same time, some essential measures such as in time reinforcing, avoiding watery process should be considered. It is helpful to promote the information design of the slope engineering.

Key words: slope engineering, characteristics of deformation and failure, time-effect character, real-time simulation
