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

Table 3

Value of proportional coefficient m of soil lateral resistance coefficient (JGJ 94-2008).

Type of foundation soil	PC piles
	(kN/m^4)	Corresponding lateral deflection of a single pile at ground surface (mm)
Muck and muddy soil, saturated collapsible loess	2000∼4500	10
Liquefied plastic (IL > 1), soft plastic (0.75 < IL ≤ 1) clayey soil, e > 0.9 silty soil, loose silty fine sand, loose and slightly dense fill	4500∼6000	10
Plastic (0.25 < IL ≤ 0.75) clayey soil, e = 0.75∼0.9 silty soil, collapsible loess, medium dense fill, slightly dense fine sand	6000∼10000	10
Hard plastic (0 < IL ≤ 0.25) and hard (IL ≤ 0) clayey soil, collapsible loess, e < 0.75 dense silty soil, medium dense medium sand, dense old fill	10000∼22000	10
