Optimization Method of Reducing the Differential Settlements of Piled Raft Foundations Based on Pile-to-Pile Interaction Theory

Table 12

The maximum pile top loads and the corresponding UBCs of different pile lengths under uniform load (MN) (Case 2).

Pmax	1	2	3	4	5	6	7	33 m
Initial design (1 <SF <2)	—	—	—	—	—	—	—	7.1
O-U	6.1	5.5	5.8	6.2	7.1	7.6	7.7	6.7
UBC	12.6	13.2	13.5	13.8	14.4	14.6	14.7	14.1

Note. P_max = the maximum load on top of the piles with the same pile length.
