Effects of Burial Depth on the Seismic Response of Subway Station Structure Embedded in Saturated Soft Soil

Model parameters of soft clay.

Soil parameter	ρ (kg/m^3)	Gref (MPa)	Bref (MPa)	c (kPa)	γmax	φ	np
Parameter value	1700	17	79	18	0.1	0	0

Note: ρ is the saturated soil mass density; G_ref is the reference low-strain shear modulus; B_ref is the reference bulk modulus; c is the apparent cohesion at zero effective confinement; γ_max is an octahedral shear strain at which the maximum shear strength is reached; φ is the friction angle at peak shear strength in degrees; n_p is an optional nonnegative constant defining variations of G and B as a function of initial effective confinement.
