Seismic bearing capacity of shallow foundations on soil reinforced by rigid inclusions
Seismic bearing capacity of shallow foundations on soil reinforced by rigid inclusions
The kinematic exterior approach, in the framework of the yield design theory, is widely utilised for assessing foundation bearing capacity. This study aims at extending this approach to shallow foundations on reinforced soil by rigid inclusions. The interaction diagram in the (V, H, M) space is obtained by combining the interaction curves derived from different failure mechanisms. The resisting forces provided by the rigid inclusions are evaluated using a multicriterion approach and are considered at the intersection of the inclusions with the failure surface. Furthermore, the soil inertia due to the horizontal seismic excitation is also considered in the analysis. The results reveal that the bearing capacity under seismic load is unaffected in the zone of interest for foundations with a sufficient safety factor under static loading.
