Mechanism Study and Tendency Judgement of Rockburst in Deep-Buried Underground Engineering
Minerals (Basel, Switzerland), 2022 Rockburst is a type of dynamic instability failure phenomenon and frequently brings huge losses to underground engineering projects such as mines and tunnels. In order to explore rockburst mechanisms and predict rockbursts better, relying on the background of Wulaofeng deep-buried highway tunnel, in situ stress measurement was performed using new ...

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,

Rockburst is an important accident scenario in deep underground engineering. Because there are numerous, complicated factors that lead to rockbursts, their forecasting is a difficult task, which, based on an engineering analogy and geological analysis, requires the use of clustering methods in rockburst forecasts.

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 ...
