... order to predict rockbursts, the cross- section marked as 6+550 which was excavated by the TUM is selected and anal- ysed computationally. From the buried depth of this section and ()v=oH, it is obtained that O"v=12.1L1MPA. It has already been known from back analysis that a'H =1.1-1.7 a'v. In...

... models and design proce- dures for linings are realized as computer programs enabling one to perform multivariant designs of un- derground structures. Reliability of the mathematical models and design procedures for li- nings is ensured both by qualitative and quantitative correspondence of the design...
