The stability of a laminated voussoir beam: back analysis of a historic roof collapse using DDA
YH Hatzor, R Benary - International Journal of Rock Mechanics and Mining …, 1998 - Elsevier
The stability of a horizontally bedded and vertically jointed roof, referred to here as a
laminated Voussoir beam, is studied using careful documentation of a historic roof collapse,
which occurred in an ancient underground water storage reservoir dated back to ca. 1000
BC The roof of the opening failed immediately after the excavation leaving a dome shaped
loosened zone, with a span of 7m and height of 2.5 m, consisting of horizontal beds and
vertical joints with mean spacing of 50 and 25cm, respectively. The ancient engineers …
