French dam collapse: rock shift was probable cause
Malpasset dam was of dome type, with curvature in vertical and horizontal sections; it was 4.9 ft thick at crest, 22.6 ft thick at base; stresses were double those considered permissble 20 yr earlier; French engineers deny that fracture planes were defective, and line of fracture merely indicates that dam broke along planes of least resistance; however, starting point of break does not sufficiently correspond with foundation shift.
