Design Characteristics of Near Surface Rock Formations
The main campus of the University of Minnesota is underlain by a flat-lying competent limestone and it, in turn, by an easily excavated sandstone. For the project, an excavation (50' wide x 100' long x 8' high) was planned. Phases I and II of the project included: installing instrumentation from the surface and from underground pilot drifts along the test room centerlines; and the development of a spray-grouting technique for in-place hardening of friable sandstone walls in rooms or tunnels. Phase III involves the actual widening of the room in stages and monitoring the response of the limestone formation to the different spans. Other aspects of the project include: preparation of a design approach for cavern roofs in jointed and laminated rocks; and encouraging the utilization of research results in general practice and demonstrating the potential of underground construction in an urban environment.
