Numerical Investigation and Design of Monopod Bucket Foundation Embedded in Sand
Numerical analysis was carried out to investigate the response and failure mechanism of monopod bucket foundation embedded in sand and subjected to eccentric lateral loading. With increasing loading height, the ultimate lateral capacity of the bucket foundation is noted to decrease, whereas the overturning moment resistance and lid centre angular rotation at failure are observed to increase. Under pure lateral load, the bucket foundation fails by dominant lateral translation, and the soil plug yields plastically resembling a shape similar to an inverted scoop above the base of the soil plug. With increasing loading height, rotational translation progressively dominates the failure of the bucket foundation, and the nature of plastic deformation gradually changes to an external upright scoop shape below the base of the soil plug. Based on the results, expressions are proposed to predict the ultimate and allowable lateral capacities of the monopod bucket foundation.
