Abstract:
It was found from experiments that most soils obey a non-associative behavior when they are subjected to shear leading to failure. The non-associative nature of soils causes less dilation rather than that predicted by an associated flow rule assumption. Practically this phenomenon results in the mobilization of smaller passive zone against failure loads applied on shallow foundations. Therefore, a relatively lower bearing capacity will be obtained if a non-associated flow rule is assumed to govern soil behavior. This study is specified to investigate the effect of flow rule on the bearing capacity of strip foundations, by employing the Drescher and Detournay [3] assumptions, formerly derived by Davis [16], in the method of characteristics. The third term has been given the most attention
