Evaluation of Undrained Bearing Capacities of Wide‐Shallow Bucket Foundation with Honeycomb Bulkheads in Clay

“…In recent years, scholars have mainly carried out experimental methods [14][15][16][17][18][19][20][21] and numerical simulations [22][23][24][25][26] to study the bucket foundation with honeycomb bulkheads. In terms of the bearing capacities, Lian et al [18] evaluated the influence of honeycomb bulkheads on the uniaxial bearing capacities by 1g model tests.…”

“…e results showed that honeycomb bulkheads have little influence on the bearing capacities when the load is relatively small, but with increasing load, the effect of the honeycomb bulkheads on the bearing capacities becomes increasingly obvious, resulting in a 6.9% enhancement in the vertical ultimate bearing capacity, 18.3% enhancement in the horizontal bearing capacity, and 16.5% enhancement in the moment bearing capacity. Sun et al [26] compared the vertical capacity and bearing characteristics between the bucket foundations with and without honeycomb bulkheads. e research results showed that the vertical bearing behaviour of the bucket foundation with honeycomb bulkheads is obviously different from that without bulkheads because of the distinctive structure of the former.…”
