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

Table 1

Detailed information about test piles (PCI-1 and PC-1).

Pile identifier	Concrete grade	PC piles			Improved soil surrounds
		Outer diameter (mm)	Wall thickness (mm)	Length (m)	Outer diameter (mm)	Length (m)
PCI-1	C80	400	95	12	800	12
PC-1	C80	400	95	12	—	—

Note. PCI = PC pile with improved soil surround; PC = PC pile without improved soil surround.
