Abstract

Abstract

Utilizing CEL (Coupled Eulerian-Lagrangian) finite element method，the penetration process of spudcan foundation was numerically simulated. The penetration mechanism of spudcan foundation into uniform clay，uniform sand and sand overlying clay was respectively explored. Through comparing the finite element predictions with available model centrifuge test results，the rationality of the proposed CEL model was validated，which showed that there existed appreciably large discrepancy in simulating deep penetration using analytical formulations based on bearing capacity theory of circular shallow foundations. The effect on the penetration resistance curve was studied to internal friction angle of upper sand and undrained strength of lower clay. The results could be of reference to design of spudcan foundation in layered soil.
