Optimization Method for Irregular Piled Raft Foundation on Layered Soil Media

Table 8

Maximum load on top of piles with different diameters (results of scheme 1) and the corresponding ultimate bearing capacity.

Pile diameter	d = 1.3 m (L = 37 m)	d = 1.4 m (L = 37 m)	d = 1.5 m (L = 37 m)	d = 1.6 m (L = 37 m)	d = 1.7 m (L = 37 m)
Maximum pile top load (MN)	8.2	9.5	11	12	13
Ultimate bearing capacity^a (MN)	15.2	16.2	17.2	18.2	19.2

^aThe empirical value calculated by equation (10).
