Influence of Sand Seismic Liquefaction on Bearing Capacity of Bucket Foundation
Abstract：The seismic analysis of bucket foundation is carried out by using ANSYS soft-ware, the sand liquefaction and the reduction of bearing capacity are calculated, and both setting-up a contact unit and using node coupling on the bucket soil interface are used in finite element model to compare the influences on the obtained results. It has been shown that the node coupling method can ensure the precision of calculation and improve the calculation efficiency. Furthermore, several bucket foundations with different slenderness are analyzed to obtain the depth of sand liquefaction and the reduction of bearing capacity, indicating that the more slender bucket foundations will benefit the bearing capacity.
