Abstract:

Analytical investigations of two problems of hardening a deep underground protective facility--1 the mechanical failure of a cavity under dynamic ground shock loading and 2 the material failure of a cavity penetration under overburden loading and repeated ground shock loading--are reported. Design requirements are derived for liner, backpacked liner, and rock bolt reinforcement, which function to prevent mechanical failure of cylindrical cavities sited in well-fractured rock and a step-by-step procedure for design is given.
