Design of an Underground Facility Subjected to CWE and Accidental Threats

Abstract

A preliminary design of a large underground facility was performed. The hardened design requirements for this facility include: penetration and ground shock due to conventional weapon effects (CWE) and impact induced ground shock due to accidental aircraft crashes. CWE threats used for the preliminary design included a 450-kg general purpose bomb and a 210-kg earth penetrating bomb. Possible accidental aircraft crash scenarios were identified based on a survey of available crash data for large commercial and military fighter aircraft. From these crash scenarios, worst case and most probable impact cases were identified. Design conservative ground shock predictions were performed. Structural response calculations using these ground shock predictions were performed to determine structural sizes and shock isolation requirements. This paper summarizes scoping calculations performed in support of the design effort.
