Horizontal Bearing Test and Optimization of Value for Precast Piles in Alluvium Stratum of the Yellow River

Table 2

Basic parameters of in situ test.

No.	Cement soil between piles				Precast pile core
	Diameter	Length	Cement content /%	mixture ratio	Pile Cross section	Pile length	Concrete type	Pile end bearing layer
	/m	/m			/m	m
PCSP1^#	1.1	24.2	16.7%	300  : 1028  : 465	0.7×0.7	24.7	C50	Clay
PCSP2^#	1.1	26.1	25.6%	500  : 900  : 550	0.7×0.7	26.6	C50	Clay
PCSP3^#	1.1	24.2	25.6%	500  : 900  : 550	0.7×0.7	24.7	C50	Clay

Note: the mixture ratio is the ratio of cement: soil: water, and the water content of the soil is 17%.
