Interpreting laboratory liquefaction test results: the importance of confining pressure to unconfined compressive strength ratios

Interpreting laboratory liquefaction test results: the importance of confining pressure to unconfined compressive strength ratios

Laboratory liquefaction testing programs on cemented paste backfills have been based on methods used in conventional geotechnical earthquake engineering. The findings from this study can be used to better design future experimental programs to assess cemented paste liquefaction potential for projects both underground and on surface.

An update to the Grabinsky et al. (2021) plug strength method

An update to the Grabinsky et al. (2021) plug strength method

Grabinsky et al. (2021) proposed an analysis method based on a failure mechanism motivated by the Prandtl approach to design structural footings in clays. Read the update to this publication.

Understanding rock mass–backfill interaction in support of deep and high-stress mining

Understanding rock mass–backfill interaction in support of deep and high-stress mining

Understanding how mining conditions induce closure onto backfill is essential, as is predicting the reaction of the backfill to passively supporting the rock mass. This paper introduces a new framework for backfill design incorporating closure conditions.
