Experimental Study on the Pile-Soil Synergistic Mechanism of Composite Foundation with Rigid Long and Short Piles

Table 3

Load sharing of composite foundation.

Types	Long pile	Short pile	Soil
Single-long-pile composite foundation	PAk1/(k1 + k3)		PAk3/(k1 + k3)
Single-short-pile composite foundation		PAk2/(k2 + k3)	PAk3/(k2 + k3)
Four-pile composite foundation	4PAk1/(2k1 + 2k2 + 4k3)	4PAk2/(2k1 + 2k2 + 4k3)	4PAk3/(2k1 + 2k2 + 4k3)
