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 Mohr-Coulomb failure criterion. A first-order correction factor is given to account for compressibility of the materials.
