| Abstract | The objective of this study was to generate data on rock properties both in situ and in the laboratory, and of the interaction between the in situ rock and the support-lining-system during the construction of a vehicular tunnel. These data could then be utilized by others to assist in determining if an appropriate tunneling method or a magnitude of load on the support-lining-system can be predicted for future tunnels. The first phase of the study involved obtaining the in situ properties of a rock mass at two locations within the tunnel. The second phase included the monitoring of the rock and/or support-lining-system to the tunnel excavation process at the location of the in situ tests. Concurrent with the field work, laboratory tests were performed on rock core specimens from the in situ test and monitoring sites. These tests provided information on standard rock properties. The data from this total study when combined with data from other tunnel studies, may assist others to improve designs and reduce cost of underground construction. Results have not indicated any new major parameter correlations. The largest loads on the support system occurred in areas of highest in situ stress and poorest in situ and core rock quality. |
