Abstract Underground excavation designs in mining and civil engineering projects are associated with a different geometric, complex ground structure, field–stresses, and groundwater conditions. Due to diverse influence factors and various requirements for each project, the design procedure should be customised based on the site-specific factors.

The Deep Underground Science and Engineering Laboratory at Homestake
AIP Conference Proceedings, 2009The US National Science Foundation and the US underground science community are well into the campaign to establish a world‐class, multi‐disciplinary deep underground science and engineering laboratory—DUSEL. The NSF’s review committee, following the first two NSF solicitations, selected Homestake as the prime site to be developed into an international,

Abstract Specimens of steel fiber reinforced concrete (SFRC) in volume ratios of 0%, 0.5%, 1% and 1.5% were prepared to study the supporting effect of SFRC at these different volume ratios in a deep soft rock tunnel. Experiments with mechanical properties of compressive strength in cubic specimens, cleave strength in cylindrical specimens and four ...

Hard rock generally performs ideal plastic character after the stress reaches its peak value with high confining pressure. Once the plastic strain satisfies certain condition, the brittle failure occurs, and the rock mass located in the residual region. Based on the mechanical model of hard rock under high confining pressure, we studied the surrounding
