| Abstract: | Based on viscoelastic theory, the behavior of a viscoelastic fixed rock plate with one free boundary is studied, and the new transform relations of viscoelastic parameters are derived in the Laplace space. The analytic formulas of the generalized Kelvin model are obtained for the fixed rock plate with one free boundary by using the new transforms, and the formulas are used to analyze the deformation of some rock cavern roof. The calculating results agree well with practical measurements and can be used for engineering reference. |
