Abstract

Foundations of towering structures are usually subjected to complex multidirectional loads. For investigating the bearing behavior of bucket foundation in soft soil under vertical-horizontal composite loading, a three-dimensional numerical model was developed in this paper. Combining the Swipe loading method and the Probe loading method, the failure mechanism of the foundation under V-H composite loading was investigated. Under the combined V-H load, the horizontal bearing capacity of the barrel foundation increased with the increase of vertical load. The foundation failure envelope was obtained, and the results shown that the envelope expands gradually with the increase of the L/D. The V-H bearing envelope obtained is found to be even smaller with no-suction interface.
