SEARCH FOR CRITICAL SLIP LINES IN FINITE ELEMENT STRESS FIELDS BY DYNAMIC PROGRAMMING. PROCEEDINGS OF THE SIXTH INTERNATIONAL CONFERENCE ON NUMERICAL METHODS IN GEOMECHANICS, 11-15 APRIL 1988, INNSBRUCK, AUSTRIA. VOLUMES 1 - 3

Finite element stresses have been combined with dynamic programming to search for the critical slip line and the associated minimum factor of safety. Solutions obtained from the present method, although falling within the framework of limit equilibrium, can allow for constitutive laws for soils or the effect of initial stresses. No assumptions have been made on the shapes of slip lines except that they consist of a chain of line segments. The shape of the critical slip line is thus given as part of the solution. The functions and features of a computer program developed for the present study are outlined. To show how this works, analyses performed with the computer program have been illustrated for two embankment problems. (Author/TRRL)
