| Abstract: | The problem of minimum overburden encountered in designing hydraulic pressure tunnel is described.The current design criteria for determining the minimum overburden are introduced.Examples of failure tunnel are to be used to illuminate the limitations of these criteria.On this basis areasonable criterion for determining the minimum overburden of hydraulic pressure tunnel is proposed. |
