The objective of the study is to develop design and analysis procedures for deep-underground hardened protective facilities in rock by considering the relative stiffness between the liner and surrounding rock and by taking advantage of the load-carrying capability of the rock mass. Accordingly, design considerations such as loading, mechanical properties of the rock mass, material properties of the liner materials, configuration of the facility, and excavation procedure are presented. Design concepts that transfer most of the applied load to the rock are presented. Detailed step-by-step design procedures, which considers rock/liner interaction are presented for rock openings with liners made from a single material, reinforced concrete liners, steel/concrete/steel conposite liners, and backpacked liners are propounded. Although the proposed design procedures were developed for hardened protective facilities, they can also be used for the design of other tunnels deep underground in rock. (Author)
