.... The experiment satisfies the similarity of geom- etry, strength, motion and boundary conditions following simulation theorem. 2.2 Experimental process Before experiment, the pressure sensors are laid into the designed positions of the model. The cor- responding weight is applied. The layout of the measurement...

..., the lower goaf roof area will increase exponentially, which may spark goaf roof to be collapsed suddenly and impact seriously on deep ore body mining. 2.2 Model establishment Based on the Saint-Venant Principle, the ore min- ing has a clear influence on a limited range of rock. Considering the boundary...

... and simplified model To complete simplify the physical and mechani- cal models, as well as control the equations of the boundary, the following points need to be assumed: 427 1. Surface crack should be a boundary connecting with the external environment, while the other boundary is deep into the rocks. 2...

... for the design of tunnel and also applied to the informative tunnel construction. The complicated geotechnical condition makes some difficulties in determination of physical and mechanical parameters of rock mass. By the finite element and boundary element methods, the obtained mechanical parameters and initial...
