Calculation Approach for Lateral Bearing Capacity of Single Precast Concrete Piles with Improved Soil Surrounds

Table 4

Detailed information of test piles (PCI-2∼PCI-4; PCI-L1∼PCI-L8).

Pile identifier	Concrete grade	PC piles			Improved soil surrounds
		Outer diameter/edge length (mm)	Wall thickness (mm)	Length (m)	Outer diameter (mm)	Length (m)
PCI-2	C80	400	95	12	800	15
PCI-3	C80	600	110	9	800	9
PCI-4	C80	600	110	9	800	9
PCI-L1, L2	C35	220	—	6	600	7
PCI-L3, L4	C35	220	—	4	600	7
PCI-L5, L6	C35	180	—	6	600	7
PCI-L7, L8	C35	180	—	4	600	7

Note. PCI-L1∼PCI-L8 are solid square PC piles with improved soil surrounds reported by Jamsawang et al. [4].
