Differences Research of Space Variability of Parameters on Surrounding Rock Deformation of Deep Laneway

摘要：

Combining theoretical analysis with numerical simulation, this paper analyzes the deformation differences of surrounding rock of deep laneway caused by space variability and randomicity of rock mass key parameters. Studies show that the deformation of deep laneway surrounding rock is influenced by the space variability and randomicity of the shear modulus and bulk modulus. The deformation of deep laneway surrounding rock is not the same, as the degree of space variability and randomicity of parameters is different, from which the inherent structural properties of rock mass are reflected, and with the increasing degree of space variability and randomicity of parameters, the deformation of deep laneway surrounding rock is increasing approximately. It is advised that those designs without considering space variability and randomicity of parameters should add support intensity for engineering safety guarantee. The conclusion has some sense to guide design and construction of the engineering.
