At present crag The stone ground foundation engineering crag body generally conforms to the increase rock mechanics condition, but side slope excavates the project and the underground project in the crag nature excavates the surface radial direction to display for the discharge condition. In the current side slope project rock mechanics analysis and the putation, uses the convention loading test parameter and the conventional this construction model and the method, does not tally very much with the actual physical model, causes the research result sand the actual monitor material not symbol, even appears the magnitude the difference. On the other hand, the discharge crag body paratively adds the Dutch crag body regarding the crag body aeolotropic characteristic and the tensile strength to be more sensitive, under the discharge condition, after specially appears the tensile stress, the structure surface mechanics condition will have the essential change, will cause the rock mechanics parameter suddenly to drop, discharge distortion sharp increase. Currently, a large number of people through the loading test and theoretical analysis, has established a series reflect the rock loading deformation and damage occurred under the theory These theoretical and applied to the engineering practices. However, the unloading and loading row with a pletely different stress path, as both of rock deformation and failure characteristics, Whether or mechanical mechanism in the mechanical response on the big difference (see table 1) therefore used for loading strength theory to predict the rock excavation works under unloading properties and the mechanical stability, obviously it is not practical. Therefore, from the theoretical and practical point of view, are necessary to carry out the works unloading rock mechanical properties studied. A study unloading rock mechanics rock mechanics is an important ponent part of the load of rock mechanics expansion and development It is a rich content of the research system, see Figure 1. The study Unloading rock mechanics as a new theory and method is still under study. At present, domestic and foreign in this area of scientific research and technological personnel also in 1996, mainly former China Yangtze River Three Gorges Project Development Corporation chief engineer Professor LingKazakhstan autumn, the Three Gorges University Professor Li Jianlin, Yichang and Chongqing University Professor Professor Jan Several researchers, these units and researchers with engineering practice, Unloading rock in the theoretical research and has been for more than 10 years. Unloading rock mechanics studies currently have the following main aspects rock engineering geological engineering geology is Unloading rock mechanics research base. The major contents of its geological structure, rock structure, surface conditions and the structure of the mutual influence, and to stress, rock classification, in particular, the structure of the situation and the advantages of the project is the impact of structural surface rock unloading mechanical characteristics as a very important one. Unloading rock mechanical properties and the parameters of rock mechanics unloading characteristics and parameters are important rock mechanics content, which includes unloading unloading the stressstrain relationship, unloading rock mechanics parameters and options. Unloading rock the size effect, anisotropy and rheological properties. In particular rock mechanics parameters identified through physical simulation, numerical simulation, engineering experience, geophysical methods based on rock unloading prehensive law to determine, experimental methods and calculations to consider conventional methods are different, it is a dynamic and evolving process. Unloading rock constitutive relations and the analytical methods of rock unloading constitutive relations and the analytical methods of disposal Council Rock Mechanics one of the core elements. It includes options to more accurately describe the mechanical behavior of rock constitutive relations, as orthotropic nonlinear constitutive relations Unloading can consider rock anisotropy nature, but a
