Charts for Preliminary Design of Deep Underground Structures Subjected to Dynamic Loads.
Abstract
This report presents charts suitable for preliminary dynamic design of deep underground protective structures in rock subjected to long-duration ground shock loadings produced by nuclear weapons. The charts were calculated using a theoretical model which consists of multilayered concentric cylinders of elastoplastic materials with a time-dependent, axially symmetric applied load representing the free-field stress. Each element in the cross section is assumed to be incompressible and its yield is governed by a Monr-Coulomb failure criterion. A first-order correction factor is given to account for compressibility of the materials. (Author)
