Equivalent parameters of drainage plates.

Parameters	E (kPa)	S (m)	υ	(m)	K (m/s)	Dx	Dz	kx (m/s)	kz (m/s)
Value	6,000	1.0	0.25	0.06	5.8 × 10^−6	1.05	0.83	6.1 × 10^−6	4.8 × 10^−6

Note. E is elastic modulus; s and υ are the spacing and Poisson’s ratio of drainage plates, respectively; d_w is the equivalent radius; k denotes the original permeability coefficient; D_x and D_z are the adjustment coefficients of horizontal and vertical permeability coefficients, respectively; and k_x and k_z are the adjusted horizontal and vertical permeability coefficients, respectively.
