Meyerhof’s Bearing Capacity Theory
|
| |
The form of equation used by Meyerhof (1951) for determining ultimate bearing capacity of symmetrically loaded strip footings is the same as that of Terzaghi but his approach to solve the problem is different. He assumed that the logarithmic failure surface ends at the ground surface, and as such took into account the resistance offered by the soil and surface of the footing above the base level of the foundation. The different zones considered are shown in fig. 2.28 |
