ABSTRACT
Over the last few decades, a number of hydraulic structures throughout the world have been experiencing operational and structural problems related to continuing alkali-aggregate reaction. Common remedial measures employed to remedy these problems include post-tensioning and/or concrete slot-cutting. In this paper, the long-term effects of slot-cutting are assessed by means of numerical analysis based on a non-linear continuum theory incorporating chemo-mechanical coupling. The analysis pertains to the junction of the concrete dam and the water intake structure of the Beauharnois power plant situated in Quebec, Canada.
