VARIABLE-FACTORS THEORY OF BEARING CAPACITY

Having reviewed the basic assumptions of various theories of bearing capacity, the theoretical basis for a variable-factor theory is established, taking into account the physical unity of the foundation soil (single slip surface) and the results from recent theoretical and experimental investigations (variable base angle). Expressions describing the variable-factors theory are developed, and general formulas for the bearing capacity factors are given. The results from solving these formulas confirm that N sub c, N sub q, and N sub gamma are variable factors dependent largely on c and phi. Graphs giving limiting values of N sub c, N sub q, and N sub gamma are presented. Application of the variable factors is explained, and its limitations are defined.
