Abstract : The matter of water inflow needs to be addressed when choosing a site for a Deep Base and constructing it. Large inflows of water could completely incapacitate the facility. The mechanisms of water inflow need to be understood to judge the suitability of a site with regard to potential water inflow problems, and estimates of inflow rates would be helpful in designing a system to dispose of unwanted water. This study has emphasized the need to develop lining systems that will waterproof the tunnel. The comment has been made that no tunnels can be made waterproof. Although common experience will support this statement, the Deep Base need not follow conventional tunneling techniques. In light of lifting cost and conventionality constraint, a few lining designs are suggested for testing for waterproof lining systems. Alternatively, the design might spawn some new, unique, and better design concepts. It is necessary to proceed with a compilation of quantified water flow experience to develop a database so that probabilistic analyses can be performed.
