Investigation of Influencing Factors on the Deformation of Sheet Pile Wall with a Relieving Platform

Table 7

Comparison of the maximum deformation of rib pillars with or without the unloading board.

Unloading board setting condition	The maximum deformation Smax (mm)	Decreasing deformation (mm)	Decreasing the percent of the deformation (%)
Without unloading board (B = 0)	22.16	—	—
With unloading board (B = 1.2 m, h = 0.9 m)	5.19	16.97	76.6
With unloading board (B = 0.5 m, h = 1.2 m)	13.23	8.93	40.3
