SIMULATION OF CRACKING IN LARGE ARCH DAM: PART I

This is the first of a 2-part presentation on a study of the mechanisms that operate in the dam-foundation region and which may be responsible for progressive cracking in the dam resulting in ultimate failure or abandonment of the structure. The study applied advanced fracture mechanics methodologies to dams with crack-type imperfections, and specifically to the upstream and downstream faces of a dam in southern Austria. This first part addresses downstream side cracking. The fracture modeling is described, and the details of the study are described. It was found that basic principles of mixed-mode, linear elastic fracture mechanics can be used to reproduce cracking observed in an arch dam. The simulation of the effects of dead load, water load, and additional loads such as grouting pressures are discussed.
