Design of rock tunnels. Phase 8

In order to study the propagation of blast wave in tunnel systems, a project started 1995 with tests in full scale and model scale. The full-scale test has been performed in a rock tunnel at the shooting range in Älvdalen. In phase 8, a full scale test with comparisons between different explosives, shape of the charge, charges with and without casing, height of centre of gravity and how the pressure wave propagates in the tunnel with different angles of incident have been conducted. The results are presented in tables and graphs.
